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.
