RFR: 8369442: ExitOnOutOfMemoryError should exit more gracefully [v2]

[Aleksey Shipilev]

> See RFE for more discussion. It seems we have a leeway in defining what "exit" means for `-XX:+ExitOnOutOfMemoryError`, and this PR does it more akin to `JVM_Halt`, rather than abrupt `os::_exit`. This gives VM a chance to shutdown some of its subsystems gracefully.
