HLSL supports typedefs, which is a much simpiler solution, and doesn't upset FXC.

When SPIRV-Cross we always reflect samplers as regular samplers. A
recent change implementing proper validation broke programs using
comparison samplers in that path.
Skip that bit of validation when using SPIRV-Cross, that hack can be
removed once we use Tint unconditionally for reflection.
Also reenables some BGL-ShaderModule compatibility tests with
SPIRV-Cross to cover the "fixed" validation.

Renames dawn_native::ComponentTypeBit to SampleTypeBit and makes
the bitmask match wgpu::TextureSampleType. wgpu::TextureComponentType
should be removed in a follow-up CL.
The Format table is augmented with float/unfilterable-float information
so that textures can be validated against the BGLEntry's
TextureSampleType.
EntryPointMetadata::ShaderBindingInfo no longer inherits BindingInfo
because the two types are diverging further. Most notably, this CL
reflects from Tint the supported SampleTypeBits for texture bindings.
This bitset is validated against the bind group layout.
Adds an isFiltering getter to SamplerBase. A filtering sampler must
not be used with a non-filtering sampler binding.
Lastly, the CL reflects sampler/texture pairs from Tint and validates
an entrypoint against the pipeline layout that a filtering sampler is
not used with an unfilterable-float texture binding.
