Sergei Golubchik 1bdaabc0c6 MDEV-35622 SEGV, ASAN use-after-poison when reading system table with less than expected number of columns ...

Relaxed check, only number of columns and the PK.
Enough to avoid crashes, but doesn't break upgrades and migration
from MySQL as in MDEV-37777.

Added checks everywhere. (flush/create/alter/drop server)

Check mysql.plugin table too.
