[master] RFR: 8301514: [Lilliput] Enable fast-locking with ZGC

Tue Jan 31 14:23:34 UTC 2023

Previously, we disabled stack-locking in ZGC because it couldn't easily deal with racy header. Now that we have fast-locking (in place of stack-locking), we can re-enable it.

Testing:
 - [x] tier1
 - [ ] tier2
 - [ ] hotspot_gc
