Speed up av1_optimize_b

1. Remove calling of get_txb_ctx from av1_optimize_b
 to it's caller, outside of rdo loops.
2. Remove calling of av1_get_tx_type, tx_type can be
 passed in by it's caller.
3. For encoder, about 1.3% faster shows by encoding
20 frame of BasketballDrill_832x480_50.y4m, with no
coding loss.  ( 601278 ms -> 592634 ms)
