The refactored CanonicalizeEntryPointIO transform makes it much easier
to handle SPIR-V style IO as well, and doing this removes a lot of
duplicated code. Remove all of the SPIR-V transform code for shader IO
and vertex point size.

Buffer allocations may need padding based on backend requirements.
GetAllocatedSize returns the size of the buffer actually allocated.
This CL also updates the backends to use GetAllocatedSize for buffer
clearing and barrier operations which should operate over the
entire allocated resource.

Fix for crbug.com/dawn/1049, where setting a pipeline without drawing can
prevent bind groups from being applied later. This occurs because the mask
for the pipeline is being saved but not its layout, because the bind
groups are never applied. This changes to only save the mask if the bind
groups are applied (the pipeline is used in a draw or dispatch).

This patch adds all the fragment builtin inputs (position, front_face,
sample_index) to EntryPoint for the validation on the total number of
fragment inputs. According to Vulkan SPEC: "All variables in both the
built-in interface block and the user-defined variable interface count
against these limits".

This is a major reworking of this transform. The old transform code
was getting unwieldy, with part of the complication coming from the
handling of multiple return statements. By generating a wrapper
function instead, we can avoid a lot of this complexity.
The original entry point function is stripped of all shader IO
attributes (as well as `stage` and `workgroup_size`), but the body is
left unmodified. A new entry point wrapper function is introduced
which calls the original function, packing/unpacking the shader inputs
as necessary, and propagates the result to the corresponding shader
outputs.
The new code has been refactored to use a state object with the
different parts of the transform split into separate functions, which
makes it much more manageable.

Some Vulkan drivers don't handle multiple entrypoints well.
In addition, SPIRV-Cross translation can be wrong for
shader modules with multiple entrypoints. Always emit a single
SPIR-V entrypoint to workaround these issues.
This allows updating CopyTextureForBrowser to use a single
shader module, and it fixes some tests with multiple
entrypoints.

Adds support for processing texture_depth_multisampled_2d bindings
reflected from Tint, and also removes Dawn restrictions against
multisampled depth. These restrictions were originally added in
https://dawn-review.googlesource.com/c/dawn/+/30240 to validate
against using a multisampled depth texture with a
comparison sampler. This is now disallowed by the language with
distinct binding types and builtins in WGSL. Previously with
SPIR-V, we inferred Depth if the texture was used
with a comparison sampler.
Also check Vulkan limits for supported sample counts.

When building a vector via tint::writer::AppendVector, and the
vector argument is already a vector constructor, expand that
vector constructor into its components only when those components
are all scalars. This avoids a type breakage which can occur with cases
like this:
vector argument is:
vec2<i32>(vec2<u32>(0u,1u))
scalar argument is:
2
Before this fix, the result was:
vec2<i32>(0u, 1u, 2);
But should be this instead:
vec3<i32>(vec2<u32>(0u,1u),2)
This was noticed in SPIR-V writer output when forming a coordinate
vector from a an unsigned WGSL coordinate vector with a signed array
vector.
