Include the GHC "Project Unit Id" in the cabal store path
- This allows the use of several **API incompatible builds of the same version of GHC** without corrupting the cabal store. - This relies on the "Project Unit Id" which is available since GHC 9.8.1, older versions of GHC do not benefit from this change. [fixes #8114]
