perf unwind arm64: Decouple Libunwind register names from Perf DWARF register numbers and real register numbers on aarch64 are equivalent. Remove the references to the register names from Libunwind so that new registers are supported without having to add build time feature checks for each new register. The unwinder won't ask for a register that it doesn't know about and Perf will already report an error for an unknown or unrecorded register in the perf_reg_value() function so extra validation isn't needed. After this change the new VG register can be read by libunwind.
