Add the ability to pick between 3 quantization profiles.
The profile is chosen based on the entropy context at the
block level.

This commit refactors the transform and quantization process for
sub8x8 blocks and unifies the related functions.

This experiment implements non-uniform quantization where
the width of the bins increases gradually to more closely
match a laplacian distribution of the coeficcients.
Performance Gain:
derflr: 0.15%
hevcmr: 0.675%

If --enable-ext-partition is used at build time, the superblock size
(sometimes also referred to as coding unit (CU) size) is extended to
128x128 pixels.

1) Add facade to quantize b/fp/dc version so that their interface
are the same.
2) Merge vp10_xform_quant b/fp/dc version to one function so that
the code flow in encodemb.c is clear
