RFR: 8375717: Outdated link in jdk.jfr.internal.JVM javadoc

[Francesco Andreuzzi]

I noticed that several javadoc entries in `jdk.jfr.internal.JVM` are still referencing `createNativeJFR`, which has been removed as part of [JDK-8310661](https://bugs.openjdk.org/browse/JDK-8310661). I propose to replace it with `JVMSupport#createJFR()`.
