Ian Rogers c4925cc8b8 perf python: Update syscall helpers and expose arch_strerrno ... Update the PyArg_ParseTupleAndKeywords format string for pyrf__syscall_name() and pyrf__syscall_id() from "i|$i" to "i|i" (and "s|$i" to "s|i"), allowing elf_machine to be passed as an optional positional argument as well as a keyword argument. Update syscall_id() and syscall_name() in perf.pyi to match, and set the return type of syscall_name() to Optional[str] as unknown syscall numbers return None. Also expose perf_env__arch_strerrno() as perf.arch_strerrno(err, elf_machine=None) so standalone Python scripts can resolve architecture-specific errno names directly from the auto-generated trace beauty tables instead of maintaining duplicate errno dictionaries in Python. Tighten the macro pattern in arch_errno_names.sh to E[A-Z0-9]+ so compiler -D flags containing underscores (such as LLVM's -DEXPERIMENTAL_KEY_INSTRUCTIONS=1) do not shadow EPERM (1), and add EM_SPARC32PLUS alongside EM_SPARC and EM_SPARCV9.
