MDEV-7660 - MySQL WL#6671 "Improve scalability by not using thr_lock.c locksbb-10.2-mdev7660

            for InnoDB tables"

Don't use thr_lock.c locks for InnoDB tables.

Let HANDLER READ call external_lock() even if SE is not going to be locked by
THR_LOCK. This fixes at least main.implicit_commit failure.

Removed tests for BUG#45143 and BUG#55930 which cover InnoDB + THR_LOCK. To
operate properly these tests require code flow to go through THR_LOCK debug
sync points, which is not the case after this patch. These tests are removed
by WL#6671 as well. An alternative is to port them to different storage engine.
