Changes TA loading and session initialization to use fine grained locking
based on the tee_ta_mutex.
This avoids a potential dead lock with PGT cache where we're waiting for
new page tables with tee_ta_mutex locked, which prevents
tee_ta_close_session() to indirectly return any page tables.
This change also removes the last really big critical section. With this
TAs can be loaded in parallel.
