perf trace beautify ioctl: Beautify perf ioctl's 'cmd' arg
Also trying a new approach, using the copy of uapi/linux/perf_event.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the perf developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.

perf trace beauty: Default header_dir to cwd to work without parms
Useful when checking the effects of header synchs for the files it uses
as a input to generate string tables, in retrospect this is how it
should've been done from day 1, not requiring the header_dir to be set
on the Makefile, will change everything later, so that the only parm,
common to all generators will be $(srctree) and $(beauty_outdir).
So, to see what it generates, just call it without any parameters:
$ tools/perf/trace/beauty/vhost_virtio_ioctl.sh
static const char *vhost_virtio_ioctl_cmds[] = {
[0x00] = "SET_FEATURES",
[0x01] = "SET_OWNER",
[0x02] = "RESET_OWNER",
[0x03] = "SET_MEM_TABLE",
[0x04] = "SET_LOG_BASE",
[0x07] = "SET_LOG_FD",

[0x21] = "SET_VRING_CALL",
[0x22] = "SET_VRING_ERR",
[0x23] = "SET_VRING_BUSYLOOP_TIMEOUT",
[0x24] = "GET_VRING_BUSYLOOP_TIMEOUT",
[0x30] = "NET_SET_BACKEND",

};
static const char *vhost_virtio_ioctl_read_cmds[] = {
[0x00] = "GET_FEATURES",
[0x12] = "GET_VRING_BASE",
};
$
Or:
$ tools/perf/trace/beauty/sndrv_pcm_ioctl.sh
static const char *sndrv_pcm_ioctl_cmds[] = {
[0x00] = "PVERSION",
[0x01] = "INFO",

[0x03] = "TTSTAMP",
[0x04] = "USER_PVERSION",
[0x10] = "HW_REFINE",
[0x11] = "HW_PARAMS",
