Use CCACHE instead of SCCACHE for HIP sources
Currently, SCCACHE does not support HIP source files, however, CCACHE does support it starting from version 4.0.
In the CI we only have one HIP build which run in a single machine (named "Forge"). Thus, we could possibly use CCACHE there by tentatively sharing a Docker volume containing the CCACHE runtime directory to the each of the jobs.
This will strongly reduce the average turnaround time.
