Sync up with current WebGPU spec to allow FS input being a
subset of VS output instead of requiring a strict match.
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.

Add a transform to truncate unused user interstage variables by
adding a new truncated shader io struct wrapper of the original
one, with a truncate function to do the assignments called
at the return statement.
This transform is meant to be run after CanonicalizeEntryPointIO,
and will only be run under hlsl/generator_impl.cc to workaround
the extra register limitation for interstage variables on D3D FXC.

Since overrides can be used to size workgroup arrays and also as
initializers to module-scope variables, we cannot just consider
overrides that are directly referenced in the shader functions.
This change makes the Resolver track references to overrides whilst
resolving array types and module-scope variable declarations, so that
they are included in the set of overrides reported by the Inspector in
these scenarios.

The MSL backend passes pointers to sub-objects to functions when
handling workgroup storage variables, which triggers the alias
analysis. Add a validation override for this scenario.
