This change refactors Difftest interfaces, replacing the previous ArchReg and WriteBack with PhyRegState and ArchRenameTable. Note when PhyReg size equals ArchReg, RenameTable can be skipped. By default, Difftest still extracts PhyReg and RenameTable into ArchReg on the hardware side, so that the extra multi-read area is accounted for within Difftest. When acceleration is enabled, this extraction is deferred to the software side, eliminating the extra hardware area overhead.
