RFR: 8343957: Rename ObjectMonitor::owner_from() and JavaThread::_lock_id

[Patricio Chilano Mateo]

Please review this small renaming patch. During the review of JDK-8338383 there were some comments about improving the naming for `ObjectMonitor::owner_from()` and `JavaThread::_lock_id`. These originate from the changes introduced to inflated monitors, where we now record the `java.lang.Thread.tid` of the owner in the ObjectMonitor's `_owner` field instead of a `JavaThread*`. I renamed `_lock_id` as `_monitor_owner_id` and `owner_from()` as `owner_id_from()`.

Thanks,
Patricio
