[jdk25u-dev] RFR: 8367949: JFR: MethodTrace double-counts methods that catch their own exceptions

[Roland Mesde]

Backporting JDK-8367949: JFR: MethodTrace double-counts methods that catch their own exceptions.

This PR fixes a bug in JEP 520's method tracing instrumentation. The current implementation incorrectly instruments throw bytecodes as method exits, causing:

1. Overcounting: Exceptions caught within the same method are wrongly counted as extra calls
2. Undercounting: Method calls aren't counted when exceptions are thrown by callees or when JVM implicit exceptions (like NPE) occur

This backport has customer demand.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=jdk_jfr
