[jdk17u-dev] RFR: 8307526: [JFR] Better handling of tampered JFR repository

[Goetz Lindenmaier]

I had to resolve three files. Two were trivial:
src/hotspot/share/jfr/jni/jfrJniMethodRegistration.cpp
src/jdk.jfr/share/classes/jdk/jfr/internal/JVM.java

Here I had to adapt code:
src/jdk.jfr/share/classes/jdk/jfr/internal/PlatformRecorder.java
shouldRotateDisc is not static in 17 because "8310661: JFR: Replace JVM.getJVM() with JVM"  is not in 17.
min_delta comes from RequestEngine because "8302883: JFR: Improve periodic events" is not in 17.
