Adds in a toggle to control using Tint or SPIRV Cross for reflection.
The current implementation only gets name and stage information via Tint,
backfilling the rest from SPIRV Cross.
Future CLs will fill in the rest of the entry point metadata.

The next commit in spirv-headers contains breaking changes that removes
the provisional ray-tracing extension and add the final version of it.
To ease the roll past that, we first roll just before the breaking
changes.
It required a roll of SPIRV-Tools and SPIRV-Cross to handle
smaller-scale breaking changes.
Also fixes a compilation issue with spirv-headers and SPIRV-Cross having
conflictin SPV_VERSION macros.

Previously Format::Type was used instead of wgpu::TextureComponentType
so that ::Other could server as a tag value. This was confusing and
almost the single use of ::Other.
In a follow-up CL the format baseType is changed to be a per-aspect
value, and Format::Type. This CL is a self-contained step in that
direction.

In addition to adding the pass running logic, how shaders are stored
in the ShaderModule is changed, so that cached shader that was used to
create the ShaderModule is differentiated from the
modified/intermediate shader that is actually being passed to
SPIRV-Cross.

This change the Metal backend in preparation for supporting multiple

- Explicitly set the spirv_cross entry point before compiling.
- Moves gathering of the local size to the frontend as it will be
useful for validation in the future.
- Query spirv-cross for the modified entrypoint name instead of
duplicating the code in Dawn.
- Move some conversion helpers from ShaderModule.cpp to their own

This patch does NOT remove the flags related to spvc usage, they are
just no-ops as the moment. After this patch lands I will remove the
usage of those flags from the bots, then remove the flags.

WGSL and SPIR-V modules can contain multiple entrypoints, for different
shader stages, that the pipelines can choose from. This is the first CL
in a stack that will change Dawn internals to not rely on ShaderModules
having a single entrypoint.
EntryPointMetadata is introduced that will contain all reflection data
for an entrypoint of a shader module. To ease review this CL doesn't
introduce any functional changes and doesn't expose the
EntryPointMetadata at the ShaderModuleBase interface. Instead
ShaderModuleBase contains a single metadata object for its single entry
point, and layout-related queries and proxied to the EntryPointMetadata
object.
Finally some small renames and formatting changes are done.

This CL adds a TypedInteger helper which provides additional type
safety in Dawn. It is a compile-time restriction that prevents integers
of different types from being used interchangably in Debug builds.
It also adds ityp::{array,bitset,span} as helper classes to wrap std::
versions (not span). These accept a template paramter as the Index type
so that typed integers, or enum classes, may be used as a type-safe
index.
For now, bind group layout binding indices use TypedInteger. Future
CLs will convert other indices to be type-safe as well.

> Revert "Check bind group layout with storage texture in pipeline descriptors"
>
> This reverts commit 63f2666ee77c987a56c6be5bfc6bbb10d12a9f63.
>
> Reason for revert: causes failures in dawn_unittests after Dawn uses SPVC by default. We need a fix in both SPVC and this CL before re-landing.

> Original change's description:
> > Check bind group layout with storage texture in pipeline descriptors
> >
> > This patch adds all the validations on the use of bind group layout with
> > read-only storage texture and write-only storage texture in the creation
> > of pipeline objects.
> >
> > 1. GPUBindGroupLayout.bindingType must match the type of the storage
> > texture variable (read-only or write-only) in shader.
> > 2. GPUBindGroupLayout.storageTextureFormat must be a valid texture
> > format that supports STORAGE usage.
> > 3. GPUBindGroupLayout.storageTextureFormat must match the storage
> > texture format declaration in shader.
> > 4. GPUBindGroupLayout.textureDimension must match the storage texture
> > dimension declared in shader.
