The new motion mode "NCOBMC_ADAPT_WEIGHT" cannot be used
in the motion search loop as it requires all mvs from the
neighboring blocks. This patch add a wrapper to skip checking
this mode during mv search.

This change does not impact the bitstream as no loss is incured by using
a fixed point value for the transform size average.

For low bit depth, the transform size average is stored using Q8.10
fixed point format. Worst case, smallest fraction is 1/1024.

When computing alpha, multiple averages are computed, one for each
transform block. The CfL prediction now uses the transform block average
instead of partition block average.

This allows the decoder to build the CfL prediction by using only the
collocated reconstructed luma values for the current transform size and
not the entire partition.

The value predicted using CfL is clipped to avoid going out of the

Subtset1.

When EC_ADAPT is enabled, this patch uses the adapted CDF after
 encoding the entire frame to compute the non-adapted costs that are
 used in RDO decision making when coding the following frame.
Future patches will update these costs periodically while coding the
 frame to keep them in sync with the actual rates used when coding the
 symbols with the adapted CDF.
