This CL adds sampling of depth-only and stencil-only texture
views on all backends. However, Metal on macOS <= 10.11 will
need a workaround to use separate depth/stencil textures for
each aspect since it is impossible to sample the stencil
aspect of a combined depth/stencil texture.
Also fixes sampling of depth24plus on D3D12 which had an
incomplete check for determining if a TYPELESS format is
necessary.

D3D debug layer uses the descriptor size (width) to
validate CBV bounds when directly allocating UBOs.
This causes validation failure when the buffer size
is misaligned (ie. not a multiple of 256B) even
through the underlying resource heap size is always
64KB aligned.
This change always aligns the buffer size to be 256B
to avoid such validation error should sub-allocation
fail.

WebGPU currently allows as many as 108 view descriptors per bind
group. This is too many to have one descriptor allocator per size,
so we need to bucket them by size.

This reverts commit c7f454c24191131eb29b8f33f0e9d5b1702fd289
and relands commit 2479860e4bb0ef5a12d269557a088bace53f0f30.

Reason for revert: We can reland this CL now that the CTS suppression merged.
Note: Adds validation to ensure binding size > 0.

Inlining these hot functions decreases CPU time in perf tests for
DrawCallPerf.Run/Vulkan by roughly 12% (55 to 47ns) and increases

This adds the formats to dawn.json, implements support in the Vulkan
backend and adds tests performing basic sampling checks for all formats.
The R8UnormSrgb and RG8UnormSrgb formats skipped because they are not
required in Vulkan (and RG8UnormSrgb is in fact not supported on the
machine used for developing this CL). A PR will be sent to the WebGPU
repo to remove the from the initial list of formats.
The RG11B10Float and RGB10A2Unorm formats of WebGPU are replaced with
B10GR11Float and A2RGB10Unorm that are the formats exposed by Vulkan. It
is likely that all APIs implement them with components stored in that
order.
Each format except depth-stencil ones is tested by uploading some
interesting texel data and checking that sampling from the texture
produces correct results. The goal is to make sure that backends don't
make a mistake in the giant switch statements. There was no effort made
to check the hardware implementation of the formats.
Tests will later be extended to cover rendering and clearing operations
as well as multisample resolve.
It isn't clear if depth-stencil format will support TRANSFER operations
in WebGPU so these are left untested for now.

This macro has some advantages over the standard library one:
- It prints the place where the macro was triggered
- It "references" the condition even in Release to avoid warnings
- In release, if possible, it gives compiler hints
It is basically is stripped down version of the ASSERT macros I wrote
for the Daemon engine in src/common/Assert.h
This commit also removes the stray "backend" namespaces for common/
code.
This directory used to contain both the state tracking code for the
backends, and the common utilities that could be used both by the
backends and the rest of the code. Things are now:
- src/common is utility code for the whole repo
- src/backend contains libNXT's code
- src/utils is utility code that we don't want in libNXT
This commit also changes all includes to use global paths from src/
bacause it had to touch a bunch of #include statements anyway.
