perf arm-spe: Add raw decoding for SPEv1.3 MTE and MOPS load/store 



Arm SPEv1.3 adds new load/store operation subclasses for Memory Tagging
Extension (MTE) and memory operations (MOPS). The memory operations
are memcpy and memset. Add support for decoding these new subclasses in
the raw decoding.
