RFR: 8280235: Deprecated flag FlightRecorder missing from VMDeprecatedOptions test [v2]

[KIRIYAMA Takuya]

> I would like to fix 8280235: Deprecated flag FlightRecorder missing from VMDeprecatedOptions test. 
> 
> FlightRecorder option has not been tested since JDK13.
> I think we should test it, because FlightRecorder option has not been obsolete in the latest JDK.
> Users would be in trouble if the option suddenly disappears without notice, 
> so it's important to confirm the deprication message.
> 
> Also we should add a test of ExtendedDTraceProbes option.
> The test was disabled in 8281675, because some jdk can't specify it.
> I modified the test to be able to verify  ExtendedDTraceProbes in either case that DTRACE_ENABLED is enabled or not.
