Allintra: Allocate obmc_buffer and comp_rd_buffer conditionally

The buffers 'obmc_buffer' and 'comp_rd_buffer' are used in inter
frames to store intermediate inter mode prediction results and
are not required for allintra encoding mode. Hence, these buffers
are not allocated for allintra encoding mode.

For AVIF image encode with speed = 6,
