Additional mat3 constructors added, global variable namespace collisions
for uniform and object color avoided via re-name.
Metal vertex format compatibility added for shaders wherein vertex data
goes through a double-conversion and cannot be implicitly converted during
Metal vertex assembly e.g. bitmasks passed directly as unsigned type in
shader interface for certain shader interfaces.

Required by Metal backend for efficient shader compilation. EEVEE material
resource binding permutations now controlled via CreateInfo and selected
based on material options. Other existing CreateInfo's also modified to
ensure explicitness for depth-writing mode. Other missing bindings also
addressed to ensure full compliance with the Metal backend.

A utility function retrieved mesh arrays for every element after
05952aa94d which can be easily avoided. This was used when
building the GPU indices for sculpt mode drawing. In my tests this
saves 0.1ms per PBVH node. There may be very slight improvements
in line art and shrinkwrap as well.
This new inheritance behavior is more beneficial for the metal Backend.
Also change the default depth write behavior of shaders to be unchanged.
This makes fragment shader depth amendment more explicit.
This also add the missing depth_write for metal kernels.
Add int attributes interpolation support for GPU subdivision.
Ensure cached shaders match their intended defines.
(The defines parameter was ignored when requesting a second time the same shader with different defines)
De-duplicate the extract_attr_init code for subdiv/non-subdiv.

Vulkan doesn't have a memory allocator builtin. The application should
provide the memory allocator at runtime. Vulkan Memory Allocator is a
widely used implementation.
Vulkan Memory Allocator is a header only implementation, but the using
application should compile a part in a CPP compile unit. The file
`vk_mem_alloc_impl.cc` and `extern_vulkan_memory_allocator` library
is therefore introduced.

This adds a vulkan backend to GHOST. The code was extracted from the
tmp-vulkan branch. The main difference with the original code is that
GHOST isn't responsible for fallback. For Metal backend there is already
an idea that the GPU module is responsible for the fallback, not the system.
For Blender we target Vulkan 1.2 at the time of this patch.
MoltenVK (needed to convert Vulkan calls to Metal) has been added as
a separate package.
This patch isn't useful for end-users, currently when starting blender with
`--gpu-backend vulkan` it would crash as the `VBBackend` doesn't initialize
the expected global structs in the GPU module.
Validated to be working on Windows and Apple. Linux still needs to be tested.

Regression introduced by {rB601995c3b86986cf8f8e5b6e5a65bcfa7f8f2e32}.
Noticed by Heist project as they render final frames with workarounds enabled.
The mentioned patch introduces attaching VBO as textures. This used to be
done by the caller. The mechanism used a different order hence the VBO
could still be unbound when using. This cannot be solved inside the new
mechanism clearly so this patch will just bind when the buffer isn't bound
just before the drawing command is sent to the GPU driver.

This implements the base needed for supporting multiple view concurently
inside the same drawcall.
The view used by common macros and view related functions is indexed using
a global variable `drw_view_id` which can be set arbitrarly or read
from the `drw_ResourceID`.
This is needed for EEVEE-Next shadow but can be used for other purpose
in the future.
Note that a shader specialization is needed for it to work. `DRW_VIEW_LEN`
needs to be defined to the amount of view the shader will access.
The number of views contained in a `draw::View` is set at construction
time.
Note that the maximum number of object correctly drawn by the shaders
using multiple views will be lower than thoses who don't.
libdecor (for window decorations) was crashing on exit with the shader
builder, avoid the crash by calling the "background" system creation
function which doesn't initialize window management under Wayland.

This patch moves the GLSL shaders and their infos to the compositor
module as decided by the EEVEE & Viewport module. This is a non

This patch adds a placeholder for the vulkan backend.
When activated (`WITH_VULKAN_BACKEND=On` and `--gpu-backend vulkan`)
it might open a blender screen, but nothing should be visible as
none of the functions are implemented or otherwise crash on a nullptr.
This is expected as this is just a placeholder. The goal is to add shader compilation
+validation to this backend as one of the next steps so we can validate
changes to existing shaders on OpenGL, Metal and Vulkan at the same time.

The bokeh blur node flipped its bokeh input due to the conceptual
difference between the search window space and the weights texture
space. This patches fixes that by inverting the weights texture to match
the search window.
The variable size option actually flips the bokeh input for the CPU
compositor. It is unclear if this is expected, so we deviate from that
behavior for now.
Adds the possibility of having a little number on top of icons.
At the moment this is used for:
* Outliner
* Node Editor bread-crumb
* Node Group node header
For the outliner there is almost no functional change. It is mostly a refactor
to handle the indicators as part of the icon shader instead of the outliner
draw code. (note that this was already recently changed in a5d3b648e3).
The difference is that now we use rounded border rectangle instead of
circles, and we can go up to 999 elements.
So for the outliner this shows the number of collapsed elements of a
certain type (e.g., mesh objects inside a collapsed collection).
For the node editors is being used to show the use count for the data-block.
This is important for the node editor, so users know whether the node-group
they are editing (or are about to edit) is used elsewhere. This is
particularly important when the Node Options are hidden, which is the
default for node groups appended from the asset libraries.

Note: This can be easily enabled for ID templates which can then be part
of T84669. It just need to call UI_but_icon_indicator_number_set in the
function template_add_button_search_menu.
