A Transform that attempts to convert WGSL `loop {}` statements into a for-loop statement.
For-loops cause less broken behavior with FXC than our current loop constructs.

This transform is intended to clean up the output of the SPIR-V reader, so that we can pattern match loops that can be transformed into a for-loop.

This behaves identically to the per-element zero-initialization, but can be significantly less verbose.

TimestampQueryTests.ResolveTwiceToSameBuffer fails on Intel latest
driver on Windows, because the kInternalStorageBuffer is not treated
in buffer usage when adding resource barrier.
Add missed kInternalStorageBuffer in buffer usage and remove
D3D12_RESOURCE_STATE_UNORDERED_ACCESS from QueryResolve, which will be
added by kInternalStorageBuffer.

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.

When indexing into vectors in a loop, FXC sometimes fails to determine
the max number of iterations when attempting to unroll the loop,
resulting in "error X3511: forced to unroll loop, but unrolling
failed.". We work around this by calling a function that sets the input
value at the input index into an inout vector. This seems to nudge FXC
enough for it to determine the number of loop iterations to unroll.

Real problem was that we relied on SymbolTable::New() to be called with
the default arg of "tint_symbol", which isn't ergonomic when forwarding
to this function from others, like TextGenerator::UniqueIdentifier().
Instead, make New() take emptry string by default, and make it use
"tint_symbol" if input arg is empty string.
Also made it so that SymbolTable::Register() must not take an empty
string, so we now assert, rather than return an invalid symbol.
