Add Validator Version to information collected by Module Metadata Analysis pass. An earlier change (#104040) added a default hardcoded value for validator version to be associated with DXIL module created during HLSL source compilation. Add tests to verify validator version info collected - Updated existing tests - Added a test with validator version specified in DXIL metadata
