perf beauty: Add a string table generator for x86's 'arch_prctl' codes 

$ tools/perf/trace/beauty/x86_arch_prctl.sh
  #define x86_arch_prctl_codes_1_offset 0x1001
  static const char *x86_arch_prctl_codes_1[] = {

	[0x1011 - 0x1001]= "GET_CPUID",
	[0x1012 - 0x1001]= "SET_CPUID",
  };

  #define x86_arch_prctl_codes_2_offset 0x2001
  static const char *x86_arch_prctl_codes_2[] = {
