At the moment there is no filter to remove any module metadata that is unrecognized by the LLVM 3.7 DXIL validator.
This results in clang producing invalid DXIL whenever a new type of module metadata is generated. To prevent this proactively we should create an allowlist that will filter out any unrecognized metadata during the `DXILTranslateMetadata` pass.
AC:
- Investigate and find all the module metadata that is recognized and used by dxil consumers
- Create the allowlist from this and add it to the `DXILTranslateMetadata`
