OPERAND_DEFINITIONStable contains 8300+ entries and it's pretty big (105 KB). For comparison allDECODER_TREE_*tables combined are around 150 KB. EachZydisOperandDefinitionentry is 13 bytes and this PR reduces it to just 5 bytes. This has been achieved by moving two major size contributors to their own deduplicated tables.sizefield has been moved toOPERAND_SIZESand saves around 40 KB (just 27 entries after deduplication).opunion is nowZydisOperandDetails(OPERAND_DETAILS) which saves another 24 KB for grand total of 64 KB saved.Most importantly this also resolves zyantific/zydis#523
