[crac] RFR: Drop perfdata and cppath

Wed Sep 27 20:49:15 UTC 2023

Storing PerfMemory contents into file might be fragile; if the file is corrupted (e.g. due to wrong permissions) JVM might receive SIGBUS when updating performance counters after restore.
This commit provides alternate solution, moving the shared file-mapped memory into private anonymous memory during C/R.
