Add speed feture to control tx size search depth

Set the max depth as 2 for speed 0.

Compression(negative means gain):
        speed 0     speed 1
lowres   -0.01%      0.00%
midres    0.05%     -0.01%
hdres    -0.01%      0.01%

Encoding speed gain:
Tested on crowd_run_1080p 30 frames
Fixed QP = 20, speed 0: 669.7s -> 656.1s
               speed 1: 104.5s -> 101.5s
Fixed QP = 40, speed 0: 440.7s -> 435.8s
               speed 1:  47.7s ->  45.1s
