This remove default casses from the `switch` statements to catch where
the missing cases are.
Uncomment unimplemented cases for the sake of completeness. Improving the
overall API.
This make the format conversion lists exhaustive and documented.
This replace `validate_data_format_mtl` by the common version as they
don't differ at all now.
For every other texture types this is expected to be implicitly
`GPU_DATA_FLOAT`. There is only one case where this is not the case.
I believe this was previously needed because the data type was
conditionning the texture creation. This is not the case anymore.
This adds a new mirror image extension type for shaders and
geometry nodes (next to the existing repeat, extend and clip
options).
See D16432 for a more detailed explanation of `wrap_mirror`.
This also adds a new sampler flag `GPU_SAMPLER_MIRROR_REPEAT`.
It acts as a modifier to `GPU_SAMPLER_REPEAT`, so any `REPEAT`
flag must be set for the `MIRROR` flag to have an effect.

Texture usage flags can now be provided during texture creation specifying
the ways in which a texture can be used. This allows the GPU backends to
perform contextual optimizations which were not previously possible. This
includes enablement of hardware lossless compression which can result in
a 15%+ performance uplift for bandwidth-limited scenes on hardware such
as Apple-Silicon using Metal.
GPU_TEXTURE_USAGE_GENERAL can be used by default if usage is not known
ahead of time. Patch will also be relevant for the Vulkan backend.

This allows the creation of texture arrays from 1D/2D/Cube texture.
This is useful when the shader expect a texture array but the original
texture isn't.
Add IMB_gpu_get_texture_format and GPU_texture_format_description to
retrieve and 'stringify' an eGPUTextureFormat. These are then used in the
image info panel used in several areas across blender.

This covers implementation of the GPUTexture abstraction for the Metal backend, with additional utility functionality as required.
Some components have been temporarily disabled pending dependencies on upcoming Metal backend components, and these will be addressed as the backend is fleshed out.
One core challenge addressed in the Metal backend is the requirement for read/update routines for textures. MTLBlitCommandEncoders offer a limited range of the full functionality provided by OpenGLs texture update and read functions such that a series of compute kernels have been implemented to provide advanced functionality such as data format conversion and partial/swizzled component updates.
This diff is provided in full, but if further division is required for purposes of code review, this can be done.

This is a necessary step for EEVEE's new arch. This moves more data
to the draw manager. This makes it easier to have the render or draw
engines manage their own data.
This makes more sense and cleans-up what the GPUViewport holds
Also rewrites the Texture pool manager to be in C++.
This also move the DefaultFramebuffer/TextureList and the engine related
data to a new `DRWViewData` struct. This struct manages the per view
(as in stereo view) engine data.
There is a bit of cleanup in the way the draw manager is setup.
We now use a temporary DRWData instead of creating a dummy viewport.

The real maximum was `GPU_SAMPLER_ICON`, not `GPU_SAMPLER_REPEAT`, my
bad. {rBa31a87f8943aa40}
Move `GPU_SAMPLER_MAX` out of the enum since it's used as an `int`
at many places.
Also, the macro `ENUM_OPERATORS` needs a maximum, and this enumerator
cannot be used as the argument of that macro. It creates wrong values
in the `~` NOT operator.

The underlying type of the enum cannot be fixed here due to its usage
in C code.
All the values possible in the width of the underlying type are not
valid for an enum.
Only 0 to (2*max - 1) if all enumerators are unsigned.
So the macro asks for the biggest value among the //listed// ones.
If any enumerator C is set to say `A|B`, then C would be the maximum.
(2*max-1) is used as the mask.
The warnings (for each enum modified in this commit):
GPU_vertex_buffer.h:43:1: runtime error: load of value 4294967291
