Move local-only variables out of global tpl stats buffers

mv and ref_frame_index are only useful for one time projection to
reference block, and ref_frame_disp_index is no longer used.
Therefore we can remove them from tpl stats array, and allocate
useful variables locally.
Reduce memory usage for 4k encoding by ~0.2G.
