RFR: JDK-8304723: Statically allocate global mutexes

Wed Mar 22 15:31:33 UTC 2023

Switch to statically allocate storage for all of Hotspot's global mutexes and monitors. This avoids needing to allocate each one dynamically at startup. These also live for the lifetime of the program, so this reduces any potential memory fragmention in the C heap.
