This unifies the codepath for high-bitdepth transforms and deletes
all calls to the old deprecated versions. This required reworking
the way 1d configurations are combined in order to support rectangular
transforms.
There is one remaining codepath that calls the deprecated 4x4 hbd
transform from encoder/encodemb.c. I need to take a closer look
at what is happening there and will leave that for a followup
since this change has already gotten so large.

This adds the proper cfgs to av1_{inv/fwd}_txfm1d_cfg for
the identity transform so all hbd transforms can use
the same codepath. This has no impact on performance
since the new identity transforms that correspond with
the cfgs are not yet being called. Once this is checked in,
we should be able to delete all deprecated transform functions
and have a single code flow for all hbd transforms.

The hbd transform configurations were originally written for all possible
2d transforms. Now that there are many more possible 2d transforms
due to EXT_TX and RECT_TX, it is simpler to write the cfg for the
4 1D transform types and compose them to make all new possible transform
types. This will allow for an easier integration of the identity transform
for EXT_TX and rectangular transforms for RECT_TX into the current
hbd transform codepath and facilitate the removal of obsolete transforms.
This has no impact on performance.
