processmanager: make ProcessPIDExit private
The recommended way to report new mappings or exited process SynchronizeProcess() should be used.

processmanager: return early in processPIDExit()
Return early from processPIDExit() if pm.pidToProcessInfo is not aware of a paritcular PID. This early return is possible, as processPIDExit() holds the global ProcessManager lock and entries in pm.pidToProcessInfo, pm.interpreters and pm.exitEvents are cleared in ProcessedUntil() while holding the lock.

The recommended way to report new mappings or exited process SynchronizeProcess() should be used.
