RFR: 8355956: Prepare javap for class file format aware access flag parsing [v2]

[Chen Liang]

> A prerequisite to #24760; this was part of it, but was split out to simplify the review of the addition of `maskToAccessFlags(int, Location, CFFV)` by minimizing the changes in javap. That patch will only need to update `BasicWriter` as a result.
> 
> Testing: langtools/tools/javap, tier 1+2 underway
