pipewire: update to latest master

Update patches:
 * remove merged patches
 * remove the alsa algorithm correction that was needed for qemu,
   as it seems to cause severe underruns on other platforms now;
   I will recheck qemu to see if this is still an issue
 * add a workaround needed to get the audioconvert plugin running
   in merge+split mode (needed to get all the channels out instead
   of just the front left channel that we were getting before)

Update version to 0.2.91 to reflect the fact that we are now tracking
the master branch instead of the work branch.

Enable the spa audiomixer plugin which is now required to mix audio on ports

+Subject: [PATCH] gst/pwaudioringbuffer: wait only for STREAM_STATE_CONFIGURE
+ when starting
+
+The CONFIGURE state is reached when the pw_client_node is exported,
+while the READY state requires the session manager to try and link
+the stream. If the SM does not want to link the stream due to policy,
+the client should not hang there forever.
+
+Upstream-Status: Submitted [https://github.com/PipeWire/pipewire/pull/140]
