RFR: 8358815: Exception event spec has stale reference to catch_klass parameter [v2]

[Serguei Spitsyn]

> The JVMTI Exception event callback spec refers to the `catch_klass` parameter which does not exist anymore. Instead the Exception event callback spec should refer to the `catch_method` and `catch_location` parameters.
> I treat this as a bug and doubt we need a CSR for this issue.
> 
> Testing: N/A
