MDEV-7943 - pthread_getspecific() takes 0.76% in OLTP RO

Pass THD to find_all_keys() and Item_equal::Item_equal(). In MRR use table->in_use instead of current_thd.

This reduces number of pthread_getspecific() calls from 354 to 320.

ok to push. although for find_all_keys() it doesn't make any sense, it's a big, complex, and expensive function. One current_thd doesn't change anything. Regards, Sergei
