tools include UAPI: Sync sound/asound.h copy

Picking the changes from:

  46b770f720bd ("ALSA: uapi: Fix sparse warning")
  a103a3989993 ("ALSA: control: Fix incompatible protocol error")
  bd3eb4e87eb3 ("ALSA: ctl: bump protocol version up to v2.1.0")
  ff16351e3f30 ("ALSA: ctl: remove dimen member from elem_info structure")
  542283566679 ("ALSA: ctl: remove unused macro for timestamping of elem_value")
  7fd7d6c50451 ("ALSA: uapi: Fix typos and header inclusion in asound.h")
  1cfaef961703 ("ALSA: bump uapi version numbers")
  80fe7430c708 ("ALSA: add new 32-bit layout for snd_pcm_mmap_status/control")
  07094ae6f952 ("ALSA: Avoid using timespec for struct snd_timer_tread")
  d9e5582c4bb2 ("ALSA: Avoid using timespec for struct snd_rawmidi_status")
  3ddee7f88aaf ("ALSA: Avoid using timespec for struct snd_pcm_status")
  a4e7dd35b9da ("ALSA: Avoid using timespec for struct snd_ctl_elem_value")
  a07804cc7472 ("ALSA: Avoid using timespec for struct snd_timer_status")

Which entails no changes in the tooling side.

To silence this perf tools build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/sound/asound.h' differs from latest version at 'include/uapi/sound/asound.h'
