libbeauty: Add a generator for x86's IRQ vectors -> strings

We'll wire this up with the 'vector' arg in irq_vectors:*, etc:

Just run it straight away and check what it produces:

  $ tools/perf/trace/beauty/tracepoints/x86_irq_vectors.sh
  static const char *x86_irq_vectors[] = {
  	[0x02] = "NMI",
  	[0x12] = "MCE",
  	[0x20] = "IRQ_MOVE_CLEANUP",
  	[0x80] = "IA32_SYSCALL",
  	[0xec] = "LOCAL_TIMER",
  	[0xed] = "HYPERV_STIMER0",
  	[0xee] = "HYPERV_REENLIGHTENMENT",
  	[0xef] = "MANAGED_IRQ_SHUTDOWN",
  	[0xf0] = "POSTED_INTR_NESTED",
  	[0xf1] = "POSTED_INTR_WAKEUP",
  	[0xf2] = "POSTED_INTR",
  	[0xf3] = "HYPERVISOR_CALLBACK",
  	[0xf4] = "DEFERRED_ERROR",
  	[0xf6] = "IRQ_WORK",
  	[0xf7] = "X86_PLATFORM_IPI",
  	[0xf8] = "REBOOT",
  	[0xf9] = "THRESHOLD_APIC",
  	[0xfa] = "THERMAL_APIC",
  	[0xfb] = "CALL_FUNCTION_SINGLE",
  	[0xfc] = "CALL_FUNCTION",
  	[0xfd] = "RESCHEDULE",
  	[0xfe] = "ERROR_APIC",
  	[0xff] = "SPURIOUS_APIC",
  };
