Tengda Wu 4c42173d98 perf dwarf-regs: Adapt get_dwarf_regnum() for arm64 ... The current arm64 DWARF register lookup relies on 'aarch64_regstr_tbl', a static string table. While this works for kprobe-tracer where register names start with '%', it is insufficient for parsing register numbers directly from raw instructions (e.g., extracting '6' from 'x6' or 'w6') during annotation. Since get_dwarf_regnum() is currently used only by 'perf annotate' and does not affect kprobe-tracer, replace the limited table-based lookup with a programmatic implementation in __get_dwarf_regnum_arm64(). This allows resolving arm64 register names (x0-x30, w0-w30, sp, etc.) directly into their corresponding DWARF register numbers.
