[vm/concurrency] Add locking for any access to [FixedCache].
...
The [FixedCache] will be accessible by multiple isolates within an isolate
group as well as the GC, so we add locking around it's accessors.
This is a preparation step for the shared heap.

Re-landing of "replace TrySync with Metadata".
...
Use that to sync variables to predefined stack
slots inside of exception handler, not before
each MayThrow() instruction.
In JIT mode we can avoid storing extra metadata
by using deopt info instead.
Introduce caching of metadata and
exception handler based on PC.
