Since the size used with cfl_load can either be based on the transform
block size and the prediction block size, width and height are used as
parameters instead of TX_SIZE.

This resolves a problem where cfl_compute_alpha_ind was reading
uninitialized memory.

Even though number of unique colors in a block may be at least
PALETTE_MIN_SIZE, sometimes the K-means can generate fewer than
PALETTE_MIN_SIZE unique centroids due to integer rounding.

This was resulting in "k - PALETTE_MIN_SIZE" being negative and using
that as an index into palette_y_size_cost array was causing a UBSan
error.

Use a simpler least-squares function for affine and rotzoom
model estimation, instead of computing the pseudo inverse.
Also refactors the code into a separate mathutils.h file.

The SVD code is currently used only for estimation of the
homography models which can be removed when we remove the
homography models.

Coding efficiency change is in noise range, with the small
difference coming from numerical precision issues.

Writes and reads alpha to and from the bitstream.

A special case is needed on the encoder side to handle prediction block
skips. Since whether or not a prediction block is skipped during CfL, a
rollback is required if the block was skipped and the alpha index was
not zero. The advantage of this is that no signaling is required when
the prediction block is skipped as it is assumed tha the alpha index is
zero.

A encode facade is added to the intra prediction facade as CfL requires
special encoder side operations.
