Validate textures with filtering/non-filtering/comparison samplers

Browse Source 
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.
