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

-Subject: pipewiresink: use all the available dest memory when copying buffer
-
-When pipewiresink needs to copy data, it has to resize the destination
-buffer (to a smaller size) in order to send the correct data size to
-pipewire. When this dest buffer is reused later, it will still have
-this smaller size as its total size and the copy may discard data
-from upstream if the new upstream buffer is bigger than the last one
-that was copied on the same dest buffer.

-Subject: pipewiresink: release manually acquired buffers back to the pool
-
-When we manually acquire buffers from the pool, we never release them.
-But because gst_buffer_pool_acquire_buffer() adds a reference to the pool,
-this leaks the pool eventually.
-
-To fix this, just unref the buffer after it has been sent. This releases
-it back to the pool and unrefs the pool.
-
-This has no significant effect to the stream, since the underlying
-pw buffers are actually pooled in the pw_stream. It just prevents leaking.
