Fixes #9616
Summary
This passes through 2 more fields from BuildXL to the project cache plugins.
MSBuildCache needs this information to do some copy tracing optimizations.
Customer Impact
Without this change, MSBuild Cache plug-ins will not be able to correlate copy source and destination events, which will prevent it from making some optimizations based on the knowledge for the specific ways files are accessed in the builds. This blocks the proposed optimizations in MSBuildCache, which is part of onboarding PowerToys and Terminal repos to use the MSBuild Cache.
Regression?
No
Testing
Manually tested that the new fields are being exposed to the plugins.
Risk
Low. This is an experimental feature and the change is additive.
