RFR: 8182774: Verify code in javap [v2]

[Adam Sotona]

> This patch adds `javap -verify` option to check the class and print obvious verification errors found.
> Implementation depends on extended Class-File API verification support, so PR #16809 is important to precede.
> The new `javap` option is mentioned in man pages and a release note will be provided.
> 
> Please review.
> 
> Thank you,
> Adam
