RFR: 8364187: Make getClassAccessFlagsRaw non-native [v2]

[Coleen Phillimore]

> This change removes the intrinsic for getClassAccessFlagsRaw for reflection and initializes an rawAccessFlags field in java.lang.Class instead, that Java code can non-natively access.
> Tested with tier1-4.

Coleen Phillimore has updated the pull request incrementally with one additional commit since the last revision:

  Rename getRawClassAccessFlags to getClassFileAccessFlags and fix the test to reflect what the JVM does.
