Add highbd_dc_top_predictor Neon implementation and tests

Add Neon implementations of highbd_dc_top_predictor for all block sizes.
Also add the corresponding tests and benchmarks.

This particular implementation is mostly a duplicate of the macro for
dc_left, however we are reading from `above` rather than `left`, and the
shift values are different since they are `log2(w)` rather than
`log2(h)`.
