jmx-dev RFR: 8369736 - Add management interface for AOT cache creation

[Mat Carter]

Add jdk.management.AOTCacheMXBean. The interface provides a single action that when called will cause any hosted JVM currently recording AOT information will stop recording. Existing functionality is preserved: when stopped the JVM will create the required artifacts based on the execution mode. Conveniently as the application running on the JVM has not stopped (as was previously the only way to stop recording), the application will resume execution after the artifacts have been generated.

The interface will return TRUE if a recording was successfully stopped, in all other cases (not recording etc.) will return FALSE

It follows that invoking the action on a JVM that is recording, twice in succession, should (baring internal errors) produce the following two responses:

TRUE
FALSE

Passes tier1 on linux (x64) and windows (x64)
