Add Neon implementations for rectangular dc predictors

We already have Neon implementations of the dc predictors for all square
block sizes, so add the remaining cases and update tests/speed to match.

On Neoverse V1, this gives a small improvement over the C code when
built with Clang 15 (~3.5%) and a significant improvement when built
with GCC 12 (~30%).
