Add Neon implementation for 64x64 dc predictors

We already have Neon implementations of the dc predictors for all other
square block sizes, so add 64x64 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 slightly better improvement when built
with GCC 12 (~8-15%).
