* 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.
