MdePkg/BaseMemoryLibOptDxe: add accelerated AARCH64 routines

Browse Source 
This adds AARCH64 support to BaseMemoryLibOptDxe, based on the cortex-strings
library. All string routines are accelerated except ScanMem16, ScanMem32,
ScanMem64 and IsZeroBuffer, which can wait for another day. (Very few
occurrences exist in the codebase)
