Update inter stage variable subsetting validation and add tests

Sync up with current WebGPU spec to allow FS input being a

This patch involves changing the validation and adding tests,
together with using the TruncateInterstageVariables for hlsl
generator to workaround the extra limit for D3D12 backend.
