pipewire: update to pw 0.3.30 and wp 0.4.0

* The pipewire recipe has been synced with the upstream yocto one
* WirePlumber configuration now has volume ducking enabled for
  navigation messages. This means that music will now duck when
  a navigation message plays instead of being corked.
* PipeWire's default configuration now lives in /usr/share/pipewire,
  with the possibility to override it in /etc/pipewire. This allows
  resetting to upstream defaults by removing /etc/pipewire

v2: add licenses to the layer to match the upstream recipe,
    adapt licenses of sub-packages
v3: mark each package with the desired license instead of the mix
v4: simplify the license output of the sub-packages
