Adjust extensions build/installation process for pg16

* Build plprofiler from source
* More extensions support pg16: plprofiler, pgl-ddl-deploy
* Small refactoring, as we don't include pg10 anymore: always
  install/build decoderbufs, pgvector, pg_mon; never install
  amcheck (it is in contrib); no need in $POSTGIS_SUPER_LEGACY.
* Remove pg_tm_aux, plantuner
* Pllua was accidentally not installed for pg15
