RFR: JDK-8222719: adjust libperfstat usage on AIX

Wed Jan 17 08:28:26 UTC 2024

Currently we use libperfstat with dlopen/dladdr, see src/hotspot/os/aix/libperfstat_aix.hpp (+cpp) .
For compatibility reason we have support for  different versions of this API.
However the AIX 5.3 / 6.1  support is outdated now, AIX versions older than 7.X are not supported any more by the current OpenJDK . So remove support for those old API versions.
