[jdk16] RFR: 8259275: JRuby crashes while resolving invokedynamic instruction

[Calvin Cheung]

Please review this proposed change which fixes 2 problems during CDS dump time:

- in `ClassListParser::resolve_indy()`, exception could be thrown from `bootstrap_specifier.resolve_bsm()` but was not handled;
- in `ConstantPool::remove_unshareable_info()`, tag was not setup correctly on error conditions.

Passed tiers 1 - 4 testing.
