This PR enabled the swapchain to be used with AMD GPUs.
The issue is that we had to separate the swapchain into
2 functions and therefore the rendering is also not
controlled at the same time.
Semaphores were finished, before being used and the
driver stalled when waiting for those Semaphores.
This doesn't solve the issue that renderdoc can still
crash the graphics driver.

This PR replaces the previous implementation of the swap chain.
The previous implementation was based on a gaming loop where
inside a single function an image is requested, the drawing occurs
and the requested image is presented on screen.
In blender the drawing isn't controlled in a single function and
this approach lead to freezes, missing frames and other
artifacts.
This approach is not be the final approach but a step into a
direction where the acquiring of the next image in the swap chain
is separated from the swapping.

Previous GHOST_ContextVK would create a logical device for each
context. Blender uses multiple contexts at the same time and wasn't able
to share resources between them as the logical device where different.
This patch will create a single logical device and share them between
multiple contexts. This allows sharing memory/shaders between contexts
and make sure that all memory allocations are freed from the device it
was allocated from.
Some allocations in Blender are freed when there isn't a context, this
was failing in the previous implementation. We didn't noticed it before
as we didn't test multiple contexts.
This patch also moves device specific data structures from VKContext to
VKDevice like the descriptor pools, debug layers etc.

In some cases comments at the end of control statements were wrapped
onto new lines which made it read as if they applied to the next line
instead of the (now) previous line.
Relocate comments to the previous line or in some cases the end of the
line (before the brace) to avoid confusion.
Note that in quite a few cases these blocks didn't read well
even before MultiLine was used as comments after the brace caused
wrapping across multiple lines in a way that didn't follow
formatting used everywhere else.
Detecting when to show warnings about GHOST/XKB modifier
mismatches was rather involved, remove the check as it's
unnecessary for Gnome-Shell >= v43.
Older versions of Gnome-Shell will show warnings on window activation
with modifier keys held.
Reading modifiers from XKB caused a complications in getModifierKeys(..)
when called on a window that was activated, before the keyboard enter
handler had run - because the keys held by GHOST had not yet been
updated by XKB. This caused a problem which Gnome-shell which runs
the keyboard-enter handler after window activation.
This change would have fixed the Super key being stuck, see: #107314.
Keep the previous fix since in the unlikely case GHOST & XKB get out of
sync, stuck modifier keys should still be prevented.
This change means the warning for GHOST & XKB getting out of sync
can be enabled for Gnome-shell again, as it was previously suppressed
as it happened frequently on window activation.
Tapping the OS key to switch windows could cause the OS key to stick.
On window deactivation the OS key was considered held, activating the
window later read the XKB modifier state before the keyboard_enter &
keyboard_modifier callbacks had run.
When they ran later, the mis-match between XKB and GHOST was not taken
into account, causing the OS key to stick.
Apparently we always constructed a Vulkan 1.0 Context, although we
are targetting Vulkan 1.2. This also lead to incorrect expectations
when using the Vulkan Memory allocator.

This PR uses the VK_EXT_debug_utils extension, but it's only for labeling, so it doesn't rely on the VK_LAYER_KHRONOS_validation functionality.
The functions that do these things are loaded into the runtime as vulkan extensions.
Declare the function pointers in a struct and make them members of vk_context.

During createOffscreenContext with VK backend enabled wl_surface
was not stored in the context's user data. This resulted in nullptr
dereference later on during disposeContext. Added a line that sets
user data and additionally added nullptr checks in disposeContext.

Expand on why front-buffer support is always disabled on Wayland &
why viewport orbit around selection offset correction isn't used for
perspective views.
- Use off-screen drawing when reading from the front-buffer isn't
supported.
- Add a capabilities flag for reading the front-buffer which is always
disabled on WAYLAND.
- Add GPU_offscreen_read_pixels_region, used for reading a sub-region of
an off-screen buffer - use for color-picking a single pixel.
After double clicking a file, user can click on a different app and
Blender will lose focus. Then it stays on splash screen. So fetch any
window instead of relying on active one to open the file.

This reverts commit 4fe2685615.
Always use the preferred_scale requested by the compositor as this
did not work so well in the intended use case (where the low resolution
monitor text was scaled down and difficult to see).
After discussion with @ZedDB, revert this change since there are cases
where either functionality might be preferred - to ensure Blender's UI
is visible on a low resolution mirrored projector for e.g.
Changing the behavior of the preferred scale makes most sense in the
compositor, instead of controlling it on a per-application basis.
Defer acting on the tag to update scale as it caused the window
to use the wrong scale on startup & exit.
GTK/KDE applications seem to postpone updating scale so use this by
default as glitches with scale tend to be caused by updating the scale
too frequently instead of not quickly enough.
There is no need to postpone these operations when configuring the frame
only postpone committing the surface change.
Deferring these operations caused flickering when moving windows
between monitors of different scale on both GNOME & KDE.
Freeing ContextEGL would attempt to free the context's EGLSurface,
which was already freed by the native-window, causing 2x bad-surface
errors on exit.
Suppress the warning by clearing the surface from releaseNativeHandles
when the surface was created by a native window.
Updating the buffer scale increased the window size based on the
previous window scale. Since the previous scale (DPI) newly created
windows restored from a `.blend` file isn't known, don't scale the
window size when updating the window's scale for the first time.
When a window overlaps multiple outputs, always use the resolution
on the output with the highest resolution. This means Blender never
shows low resolution content up-scaled.
Share logic between fractional & non-fractional window scaling.
This also enables fractional-scaling without scaling fixed sized buffers
for compositors without support for fractional_scale_manager_v1.
Logic for the recently included fractional scaling support [0] was
difficult to reason about as it depended on two different callbacks
one that listened to a preferred scale, another that tracked which
physical displays the window overlapped.
Checking if fractional scaling was in used depended on the order
the callbacks ran - which is undefined.
In practice - mixing non-fractional and fractional displays would
flicker when the window was moved between monitors.
Resolve this problem with the following changes:
- When the fractional-scale manager is supported,
only respond to the scale from it's preferred_scale callback.
- When no fractional-scale manager is available,
set the scale based on the scale of overlapping outputs.
- Add support for postponing the buffers commit call to prevent
flickering when changing the windows scale.
Other changes:
- Use a lock before setting the pending frame state from
wp_fractional_scale_handle_preferred_scale.
- Ensure pending actions that themselves trigger pending actions
run in the time gwl_window_pending_actions_handle is called.
- Rename GWL_Window::scale -> GWL_WindowFrame::buffer_scale.

Depend on fractional-scale when searching for wayland-protocols
This will impact builders that don't use Blender's `../lib/` and
have wayland-protocols older than v1.31.
Previously, fractional scaling was detected but set an integer buffer
scale which the compositor would down-scale causing blurry output.
Now the fractional scaling interface is used when available to set the
DPI and set the internal buffers size & viewport transformation to
ensure 1:1 pixels from Blender to the Wayland output.
Tested to work with multiple monitors with mixed
fractional/non-fractional scale.
Note that this change causes a regression for when fractional scaling
is set on a compositor without support for fractional-scale-v1.
Supporting fractional scaling in both cases is possible but overly
complicated. This case already wasn't working so well - with blurry
output due to image scaling, now the DPI wont be accurate in this case
although Blender is still usable.
The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
For example
```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```
becomes
```
OIIOOutputDriver::~OIIOOutputDriver() {}
```
Saves quite some vertical space, which is especially handy for
constructors.

The DPI returned by the GHOST/Wayland didn't account the buffer being
rendered at a higher (non-fractional) resolution, then scaled down.
This caused the software cursor and UI to rendered very small.
A fractional scale of 101% would show the UI just over 50% of the size
(making the UI to be close to half the scale it should have been).
Resolve by accounting for down-scaling of the buffer to it's
fractional size.
This PR adds pre-checks when enabling validation layers.
For validation layers to work some platforms require that
the Vulkan SDK is installed. Validation layers are activated
when running blender with `--debug-gpu`.
Sometimes we expect users to run with `--debug-gpu` for
narrowing down an issue and we cannot expect them to have
the Vulkan SDK installed.
This patch will check if the `VK_LAYER_PATH` is available
and that the configuration file of the validation layer is
present. If this isn't the case we don't activate the
requested validation layer.

Calling render (for example) with an existing window open now activates
the window on Wayland. Tested to work on GNOME & KDE.
Use the xdg-activation protocol which typically brings the
window to the foreground.
