RFR: 8330684: ClassFile API runs into StackOverflowError while parsing certain class' bytes [v2]

[Adam Sotona]

> ClassFile API dives into the nested constant pool entries without type restrictions, while parsing a class file. Validation of the entry is performed post-parsing. Specifically corrupted constant pool entry may cause infinite loop during parsing and throws SOE.
> This patch resolves the issue by providing specific implementations for the nested CP entries parsing, instead of sharing the common (post-checking) code.
> Added test simulates the situation on inner-looped method reference entry.
> 
> Please review.
> 
> Thank you,
> Adam
