MDEV-4262 - P_S discovery

Browse Source 
Discover P_S tables automatically.

Most of this patch is code clean-up:
- removed tests and code responsible for P_S tables correctness verification
- always return error from ha_perfschema::create()
- install/upgrade scripts won't create P_S tables anymore
