RFR: 8364660: ClassVerifier::ends_in_athrow() should be removed [v2]

[Matias Saavedra Silva]

> The logic located in `ClassVerifier::ends_in_athrow()` is no longer required by the JVM Spec as of Java SE 22 (see JVMS 4.10) and the error cases should be handled by the stack map table and its rules for `uninitializedThis`. Thanks to that, `ClassVerifier::ends_in_athrow()` and any relevant code can be removed. Verified with tier1-5 tests.
