[tblgen][disasm] Separate encodings from instructions
Summary: Separate the concept of an encoding from an instruction. This will enable the definition of additional encodings for the same instruction which can be used to support variable length instruction sets in the disassembler (and potentially assembler but I'm not working towards that right now) without causing an explosion in the number of Instruction records that CodeGen then has to pick between.
