Optimize allocation of MI buffers

A single partition size(16X16) is used in the stats generation
stage(firstpass/LAP), however MI buffers are allocated memory for
4X4(or 8X8 if res >=4k). Changed alloc_bsize of MI to 16x16 in stats
generation stage to reduce the memory footprint of firstpass/LAP.

Observed memory footprint reduction in singlepass AOMQ.
