RFR: 8340415: Update failure handler to print more info using gdb scripts

Thu Sep 19 03:12:08 UTC 2024

The failure handler updated to use gdb scripts.
The initial version print some information about mutextes, safepoint and threads state. So the deadlocks are easier to analyze without opening core files.
The existing gdb processing is not changed.

Later the script might be improved with more information.
