MDEV-36476 MDEV-35452 Disable view protocol for spider tests where thread metadata could prevent lock wait timeout

Browse Source 
In spider/bugfix.mdev_29352, with flush tables with read lock,
statements blocked in THD::has_read_only_protection() by checking
THD::global_read_lock could result in view protocol to "hang" waiting
for acquiring mdl in another THD.

In spider/bugfix.mdev_34555, within an XA transaction, statements
blocked by trans_check() by checking thd->transaction->xid_state could
result in view protocol to "hang" for the same reason.

Therefore we disable view protocol for relevant statements in these
tests.
