When creating a texture view, Metal may require that the original
GPUTexture state is modified in some way. This may be a result
of deferred creation, or, to cache the texture view against the
source.
As a result, GPUTexture passed into GPU_texture_create_view
cannot be const.
Small fixes have also been made in the Metal texture
implementation to ensure correct function of texture views.

This PR adds support for `GPU_unpack_row_length_set` to the vulkan
backend.
Texture unpacking is used when uploading a part of a texture from
host memory to device memory.

Changes to the internal workings of the VKCommandBuffer:
- Use state engine to track correct usage.
- Switch between render pass/no render pass automatically.
Eventually the command buffer should be rewritten to use custom command
encoding to improve performance.

In the GPU_SHADER_2D_WIDGET_BASE the deriviates were assumed to be
positive. This is not always the case. In Vulkan this leads to
incorrect rendering of the widgets due to incorrect SDF values.
This change will ensure that the shader make the ratio variable
absolute.

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.

Add texture usage flags for textures which are used as texture views
or require texture views for backing implementation.

Leverage new API call in Metal to increase the number of threads
dedicated to concurrent shader compilation. First step to improve
parallel compilation times when multiple engines are active.
Would also enable an increase in worker threads for shader
compilation jobs within the DRWManager.
Note that this is only available in the latest
version of macOS Ventura (13.3).

Shader source requires explicit conversions and shader address
space qualifers in certain places in order to compile for Metal.
We also require constructors for a number of default struct types.

- 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.
Currently the Textures used for offscreen rendering don't have
the `GPU_TEXTURE_USAGE_HOST_READ` flag. But some cases it is
needed. This PR adds a parameter when creating an offscreen
buffer.
Other solution could be to add this flag to all textures, but
we chose not to do this as that reduces the amount of fine-tuning
options for Metal/Vulkan backends. GPU can store textures
differently based on its actual usage.
This option isn't available in the python API as we don't expect
add-on developers to fine-tune texture usages to this extent.
For convenience `GPU_TEXTURE_USAGE_ATTACHMENT` is by default
always added.

Vulkan uses IMath. IMath on windows requires an option to indicate
it is used as dll file. This option wasn't set for the GPU module.
Thanks to Kazashi Yoshioka for mentioning this.

Previous fix to resolve GPU hang which could occur in the
Metal backend caused additional flickering to occur as
as side effect, due to removal of required execution
dependencies in certain places.
This patch resolves both problems by only removing the
GPU hang dependency stall when additional synchronization
primitives are used along-side the global sync primitive.

This function was not exposed outside of internal GPU module.
Renaming `draw::Texture::depth()` to `is_depth` for consistency
and removing the ambiguity.
Changes to viewport state to resolve texture paint color
selection introduced a side effect wherein the correct
attachment size of a framebuffer was reset. This size is
needed when scissor regions are disabled to return the
state to its correct default. When this default was wrong,
certain operators would have incorrect offsets.
To maintain consistency with the OpenGL backend, the
Metal backend independently tracks the raw attachment
size using default_width/height. This will also reset to zero
when attachments are all removed, unlike other state which
may be retained.

This checkin will use OIIO to replace the image save/load code for BMP,
DDS, DPX, HDR, PNG, TGA, and TIFF.
This simplifies our build environment, reduces binary duplication,
removes large amounts of hard to maintain code, and fixes some bugs
along the way.
It should also help reduce rare differences between Blender and Cycles
which already uses OIIO for most situations. Or potentially makes them
easier to solve once discovered.
This is a continuation of the work for #101413

Issue caused by inconsistency in GPUFramebuffer viewport state
between Metal and OpenGL. The MTLFramebuffer code has been
modified such that framebuffer viewport/scissor state is retained
and only updated if attachments are modified during bind.
This is consistent with OpenGL. Previously, other updates to the
framebuffer in Metal would reset the viewport region, especially
if attachments were temporarily removed. This caused the color
picker selection to be misaligned.

After investigating the crash logs it looked like the macro
unrolling wasn't working on Windows systems with these GPUs.
Macro unrolling was changed in order to cross compile to Metal and
in the future to Vulkan. The macro unrolling in OpenGL can be removed
by using a different naming scema.
This PR removes the macro unrolling by changing the generated GLSL
code:
**Before**
```
layout(std140) uniform _probe_block
{
ProbeBlock probe_block;
};
```
**After**
```
layout(std140) uniform probe_block
{
ProbeBlock _probe_block;
};
```
Some tweaks had to be done to the Eevee-shaders to make sure that
the macro unrolling is done correctly and could be compiled using
legacy opengl drivers.

This PR adds debug information inside the spir-v assembly to enable
step-by-step debugging of Shaders using renderdoc. The debugging
information can be fairly large so are only generated when used
with the `--debug-gpu-renderdoc` feature.
During debugging shader optimizations are turned off.

This patch refactors the texture samples code by mainly splitting the
eGPUSamplerState enum into multiple smaller enums and packing them
inside a GPUSamplerState struct. This was done because many members of
the enum were mutually exclusive, which was worked around during setting
up the samplers in the various backends, and additionally made the API
confusing, like the GPU_texture_wrap_mode function, which had two
mutually exclusive parameters.
The new structure also improved and clarified the backend sampler cache,
reducing the cache size from 514 samplers to just 130 samplers, which
also slightly improved the initialization time. Further, the
GPU_SAMPLER_MAX signal value was naturally incorporated into the
structure using the GPU_SAMPLER_STATE_TYPE_INTERNAL type.
The only expected functional change is in the realtime compositor, which
now supports per-axis repetition control, utilizing new API functions
for that purpose.
This patch is loosely based on an older patch D14366 by Ethan Hall.

Renderdoc requires all calls/updates to originate from the same
context. It also doesn't support multithreading. For now we
enable main context workaround.
The renderdoc integration used to be behind the `--debug-gpu`
command line option. When using `--debug-gpu` outside renderdoc
error messages where displayed that aren't relevant.
This PR adds a specific command line option for the renderdoc
integration. This option will also enable `--debug-gpu`.
