rewrite 0f-based instruction handling
this is... a more significant rewrite than i expected yaxpeax-x86 to ever need. it turns out that capstone is extremely permissive about duplicative 66/f2/f3 prefixes to the point that the implemented prefex handling was unsalvageable. while this replaces the *0f* opcode tables, i haven't profiled these changes. it's possible this is a net improvement for single-byte opcodes, it could be a net loss. code size may be severely impacted. there is still work to do. but this in total gets very close to iced/xed/zydis parity, far more than before. also adds several small extensions, gfni, 3dnow, enqcmd, invpcid, some of cet, and a few missing avx instructions.
