yaojiaqi 131f7f75ed arm: memcpy: add NEON paths for aligned copies 
Add dedicated NEON implementations for mutually aligned medium and long memcpy copies when building with __ARM_NEON__. These paths use NEON multi-register loads and stores while preserving the existing VFP implementation for non-NEON VFP configurations.

NEON builds also define USE_VFP, so select the NEON implementation explicitly before falling back to VFP. Apply the same aligned-copy optimization to the armv7-a, armv7-r, and armv8-r implementations.
