Added JavaFlightRecorder options for Tests

[AndreasTu]

This allows you to create JFR recordings with the flag -Pjfr when running Gradle Test tasks.

The jfr_config.jfc provides a profiling config for the JFR. It tracks the TLAB allocations in addition to the normal profiling config in JDKs (JDK/lib/jfr/profile.jfc). It has also the following changes:

• Method sampling interval of 2 ms
• Thread dump interval of 10 s
• CompilerInlining true
• ObjectAllocationSample throttle 1000/s
• JavaExceptionThrow true
