RFR: 8145153: Convert TraceMonitorInflation to Unified Logging

[Rachel Protacio]

Hello!

Please review another product flag logging change. This one's pretty 
small. Converts TraceMonitorInflation to -Xlog:monitorinflation=debug 
internally, with an alias for the old option. I've again patched in 
Max's alias table code in the arguments.cpp and .hpp files since my 
previous changeset with that code is currently on hold.

Bug: https://bugs.openjdk.java.net/browse/JDK-8145153

Testing: passes jck vm tests, JPRT, and RBT quick and noncolo tests

Thank you!
Rachel
