D3D12: implement WGSL pipeline cache key generation

Since spirv_to_dxil does not generate HLSL, to support pipeline caching,
we need to generate a cache key from the WGSL instead.

A new type, ShaderCompilationRequest, is added to isolate the
compilation inputs to help ensure that the cache key contains all
relevant information.
