rcutorture: Allow per-RCU-flavor polled double-GP check

Only vanilla RCU needs a double grace period for its compressed
polled grace-period old-state cookie.  This commit therefore adds an
rcu_torture_ops per-flavor function ->poll_need_2gp to allow this check
to be adapted to the RCU flavor under test.  A NULL pointer for this
function says that doubled grace periods are never needed.
