Refactor hbd txfm configurations to be 1D 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. BUG=aomedia:524 Change-Id: I1e217bcd217fd637b1df94fae62d9c59a0523c1a

Add configurations for hbd identity transform 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.
