RFR: 8329138: Convert JFR FileForceEvent to static mirror event [v6]

[Tim Prinzing]

> Currently the JFR event FileForceEvent is generated by instrumenting the sun.nio.ch.FileChannelImpl class. This needs to be changed to use the newer mirror events with static methods.
> 
> Added the event at jdk.internal.event.FileForceEvent, and changed jdk.jfr.events.FileForceEvent to be a mirror event.
> 
> Updated FileChannelImpl to use the jdk internal event static methods, and removed the force() method from FileChannelImplInstrumentor.
> 
> Uses the existing tests.
