Add Neon implementation of high bitdepth MSE functions

Add an Armv8.0 and Armv8.4 Neon implementation of high bitdepth MSE
functions for each 8-, 10- and 12-bit data and use it instead of
falling back to the scalar C function.

The implementation of the functions is a backport of this libvpx
change[1].

Add the corresponding tests as well.
