Avoid unnecessary out of boundary access issue.

Change-Id: I949372827a7b5133428a45af0ab2be03aa30a742

MAX_NUM_TXB represents the maximum number of transform blocks in 1
dimension. CfL requires the maximum number of transform blocks in 2
dimensions. As such, we now use MAX_NUM_TXB_SQUARE instead of the
erroneous MAX_NUM_TXB for the average buffer.

There's an assert guarding for overrun on the average buffer.
This fix stops assertions on 4:4:4 sequences. This patch does
not alter AWCY results as AWCY only covers 4:2:0 sequences (for
which MAX_NUM_TXB turns out to be sufficient).

Added CFL_SUB8X8_VAL_MI_SIZE and CFL_SUB8X8_VAL_MI_SQUARE to replace the
magic numbers previously used. Also, CFL_SUB8X8_VAL_MI_SIZE goes from 2

Recent code added in EXT_INTRA wasn't compatible with CfL,
because it assumed that the PREDICTION_MODE was the same
for luma and chroma, which is not the case with CfL.

UV_PREDICTION_MODE must be converted to PREDICTION_MODE for
av1_is_directional_mode function.

The error-resilient-mode flag is currently set per frame,
so we can encode a non-error-resilient frame immediately
after an error-resilient frame.

As of https://aomedia-review.googlesource.com/c/21783 , this
case causes the decoder to read uninitialized memory. This
happens because the error-resilient frame no longer sets up
cm->cur_frame->global_motion. Then, on the non-error-resilient
frame, that is renamed to cm->prev_frame->global_motion and we
try to use it as a reference for delta encoding.

Fix this by always writing cm->cur_frame->global_motion.
