RFR: 8307532: Implement LM_LIGHTWEIGHT for Zero [v2]

[Roman Kennke]

> This implements the remaining parts of LW locking in Zero. Much of the work has already been done by Axel, this basically only implements the missing part that handles synchronized JNI entries. I basically preserved the LM_LEGACY case, except that I shuffled the code a little to match what we do in monitorexit case in bytecodeInterpreter.cpp (but should be functionally equivalent). The LM_LIGHTWEIGHT and LM_MONITOR case (the latter of which has been broken, before) simply call into the runtime.

> With this change, we can now remove the block in arguments.cpp that deals with missing LM_LIGHTWEIGHT support.

> Testing:
>  - [x] bootcycle-images
