AOT code caching fixes:
- added Xlog info when AOT code caching starts and finishsX
- call CDSConfig::disable_dumping_aot_code() before we close
AOT code cache: to avoid AOT compilation after cache is closed
- small code reordering in AOTCodeAddressTable::init_extrs()
- fixed Zero build on Aarch64 (relocation.hpp changes)
- adjusted compiler threads count setting for AOT assembly phase
- fixed merge mismatch: double call to TrainingData::initialize()
