[lworld] RFR: 8361082: [lworld] RewriteBytecodesInlineTest fails with SIGSEGV [v8]

[Matias Saavedra Silva]

> `RewriteBytecodesInlineTest` fails after # due to a new log message printing the pending exception name even though there may not be a pending exception:
> `PENDING_EXCEPTION->klass()->name()->as_C_string()`
> 
> This patch refactors the loadable descriptor handling used in `SystemDictionary::load_shared_class` to better illustrate how the loadable descriptors property is handled and it corrects the log messages to be consistent with the messages used in the class file parser. Verified with tier 1-5 tests.
