Add specific path for horizontal dirs in cdef_find_dir_neon

compute_directions was used for both vertical and horizontal directions,
with a rotation of the input block between the two calls. Remove the
rotation and add a specific function to compute horizontal directions.
This gives around 9% uplift for cdef_find_dir for both Clang and GCC.
