[master] RFR: 8299594: [Lilliput] Revert "Replace stack-locking with fast-locking"

[Roman Kennke]

I'd like to revert the original fast-locking change and later replace it with the reworked fast-locking (https://github.com/openjdk/jdk/pull/10590). This new version can be turned on/off by a runtime flag, and is also more efficient, because it doesn't need to check the lock stack size on every monitorenter.

The revert is clean.
Testing:
 - [x] local build
