Implement aom_sse_neon helpers using UDOT instruction

Accelerate the aom_sse_neon helper functions using the Armv8.4-A UDOT
instruction instead of multiple UMULL and UADALP instructions.

The previous implementation is retained for use on systems that do
not support the Armv8.4-A dot-product instructions.
