RFR: 8336017: Deprecate java.util.logging.LoggingMXBean, its implementation, and accessor method for removal

[Kevin Walls]

java.util.logging.LoggingMXBean and java.util.logging.LogManager::getLoggingMXBean are deprecated since JDK-8139982 in JDK 9.

These deprecations should be uprated to state they are for future removal.

java.util.logging.Logging (implements LoggingMXBean) should also be deprecated for removal.
