pipewire: Rework 0.3 recipe and upgrade to 0.3.22

* Use a versioned recipe instead of _git
* Add more packageconfigs: alsa, docs, sdl2, sndfile, v4l2,
  pipewire-alsa, pipewire-jack
* Split SPA and module packages dynamically to generate one package for
  each SPA plugin and for each module
* Split pipewire library, shim PulseAudio daemon, main tools & SPA tools,
  pipewire-alsa, pipewire-jack, ALSA card profiles, GStreamer plugin,
  and example session manager into separate packages
* Set up a "pipewire" user and group to run the PipeWire daemon with that
  user instead of root
