Allocate mbmi_ext at BLOCK_8X8 level for 4k+ videos

Previously mbmi_ext is dynamically allocated at the beginning for each
BLOCK_4X4. This change makes the allocation resolution dependent, so it
is allocated for each BLOCK_8X8 instead.

Memory Reduction:
About 1GB for 4K videos, which is about 25% of heap memory.
