RFR: 8351046: Rename ObjectMonitor functions [v4]

[Coleen Phillimore]

> This change simply changes the remaining names of functions in objectMonitor that were camel case, now following the hotspot coding standard.  Recent changes have been confused about which style to use, so this helps with this.  This is a mechanical change, largely trivial.  Further improvements can be different PRs, but any names missed could be added to this.
> Ran tier1 on Oracle standard platforms.

Coleen Phillimore has updated the pull request incrementally with one additional commit since the last revision:

  Rename WaitSet, WaitSetLock and SpinDuration to follow hotspot coding style.
