Add WebGPU specific validation for Position BuiltIn decoration (#2309)

Browse Source 
This CL adds in the specific checks required for WebGPU, enables
running the builtin checks for WebGPU, and refactors the existing
testing infrastructure to support testing the new checks.

This PR is part of resolving #2276
