This fixes the mis-aligned cdf model derived from tree based
model. It resolves the compression performance regression in
dual filter, intra mode, inter mode, and transform block type
coding, when ec-multisymbol is enabled by default.

With dual filter enabled, the performance regression was 3.6%
loss for lowres. This fix brings the performance gains back to 1%
gains.

Currently, mbmi->ref_mv_idx can be set to a nonzero value
on the encoder side if mbmi->mode is one of NEARMV, NEWMV,
NEAR_NEARMV, or NEW_NEWMV. But it can only be nonzero on the
decoder side if the mode is NEARMV or NEWMV. Hence av1_nmv_ctx
has previously been disabled when ext-inter is enabled, to
prevent a mismatch due to this.

This patch changes the encoder behaviour to match the decoder
behaviour.

Use a simpler warped motion estimation scheme that uses a 2d
least squares problem, where the underlying assumption
applied is that the motion vector computed at the center
of the current block using the warp model is exactly the same
as the motion vector transmitted for the block.

The main motivation is to reduce the complexity of the
estimation process.

Coding efficiency drop is about +0.25% on lowres:
-1.152% (from -1.396%).

Also, removes code for non-approximate division and bakes
approximate divison in.
