RFR: 8260193: Remove JVM_GetInterfaceVersion() and JVM_DTraceXXX [v2]

[Ioi Lam]

> - JVM_GetInterfaceVersion() was used by "HotSpot Express" (HSX) which allowed the same JDK library to use different version of HotSpot. However, HSX is no longer supported so this API should be removed.
> - Implementations of APIs such as JVM_DTraceActivate, were removed in [JDK-8068976](https://bugs.openjdk.java.net/browse/JDK-8068976), so their declarations should be removed from jvm.h
