RFR: 8252543: [JVMCI] Libgraal can deadlock in blocking compilation mode [v3]

[Doug Simon]

> To prevent a deadlock in libgraal under `-Xcomp` or `-Xbatch` due to a lock being held in libgraal, a new mechanism is
> added by this change that allow JVMCI compiler threads to communicate their "progress" to HotSpot:
> * Each JVMCI compiler thread has a "compilation ticks" counter.
> * There is also a global JVMCI compilation ticks counter.
> * Each JVMCI VM call increments the JVMCI compiler thread-local compilation ticks counter.
> * Every 512 increments of such a counter also increments the global counter.
> * A thread waiting on a blocking JVMCI compilation will be unblocked if these counters indicate no progress after a
>   defined period.
