* Allow unconsumed inputs in fragment shaders by removing them from vertex
outputs when generating HLSL.
Fixes https://github.com/gfx-rs/wgpu/issues/3748
* Add naga:🔙:hlsl::FragmentEntryPoint for providing information
about the fragment entry point when generating vertex entry points via
naga:🔙:hlsl::Writer::write. Vertex outputs not consumed by the
fragment entry point are omitted in the final output struct.
* Add naga snapshot test for this new feature,
* Remove Features::SHADER_UNUSED_VERTEX_OUTPUT,
StageError::InputNotConsumed, and associated validation logic.
* Make wgpu dx12 backend pass fragment shader info when generating
vertex HLSL.
* Add wgpu regression test for allowing unconsumed inputs.
* Address review
* Add note that nesting structs for the inter-stage interface can't
happen.
* Remove new TODO notes (some addressed and some transferred to an issue
https://github.com/gfx-rs/wgpu/issues/5577)
* Changed issue that regression test refers to 3748 -> 5553
* Add debug_assert that binding.is_some() in hlsl writer
* Fix typos caught in CI
Also, fix compiling snapshot test when hlsl-out feature is not enabled.
* naga: glsl parser should return singular ParseError similar to wgsl
* wgpu: treat glsl the same as wgsl when creating ShaderModule
* naga: update glsl parser tests to use new ParseError type
* naga: glsl ParseError errors field should be public
* wgpu-core: add 'glsl' feature
* fix some minor bugs in glsl parse error refactor
* naga/wgpu/wgpu-core: improve spirv parse error handling
* wgpu-core: feature gate use of glsl and spv naga modules
* wgpu: enable wgpu-core glsl and spirv features when appropriate
* obey clippy
* naga: derive Clone in Type
* naga: don't feature gate Clone derivation for Type
* obey cargo fmt
* wgpu-core: use bytemuck instead of zerocopy
* wgpu-core: apply suggested edit
* wgpu-core: no need to borrow spirv code
* Update wgpu/src/backend/wgpu_core.rs

Following Rust convention, let `naga::front::wgsl::ParseError`'s
methods `emit_to_stderr_with_path` and `emit_to_string_with_path`
accept any `AsRef<Path>` argument as the path.
Pass input paths in snapshot tests, so that failures processing
shaders name the input file being processed.
