Add speed feature prune_ref_frame_for_gm_search

Introduce a speed feature for cpu-used >= 2, to prune
reference frames during global motion estimation.
This speed feature will prune ref frames in a direction (past/future)
if the farthest ref_frame in that direction yields gm_type as
INVALID/TRANSLATION/IDENTITY.
