RFR: 8317422: [JVMCI] concurrency issue in MethodData creation

[Doug Simon]

`Method::build_profiling_method_data` is the safe way to create `MethodData` for a `Method` - it uses an atomic to do the write.
This PR updates `c2v_getFailedSpeculationAddress` and `c2v_reprofile` to use `Method::build_profiling_method_data`.

-------------

Commit messages:
 - replace set_method_data with clear_method_data
 - use Method::build_profiling_method_data in JVMCI
