RFR: 8294978: Convert 5 test/jdk/jdk/jfr tests from ASM library to Classfile API [v6]

[Chen Liang]

> Converted these tests to Classfile API and some of the constants to Constant API. InstrumentationCallback.callback wasn't changed to a record since I cannot figure out how to ship a nested record class with InstrumentationCallback in a jar.
