pipewire: update pipewire & wireplumber to the latest development version

This refreshes all the patches, removing all those that made it upstream, redoing the endpoint extension (now called session-manager extension), and adding some more last moment fixes. In addition, the configuration files for wireplumber & pipewire are being updated to load the new modules, as the module set has changed in both daemons. Finally, the pipewire recipe is adding PACKAGECONFIG options for jack and vulkan, so that we can actually disable them. Pipewire upstream builds them by default and we don't want that.

+ work
+
+This bug appeared when testing bluez-alsa nodes with pipewire.
+bluez-alsa exposes also non-interleaved formats and if such a format
+is picked, then nothing works because the converters are not working

-Subject: [PATCH] audioconvert/fmtconvert: assume F32 on the other port when
- listing formats
-
-This allows picking F32LE as the default format on links that have
-no restriction and it avoids failing negotiation when the restricted
-end cannot handle S16/F32/F32P
-
-For instance this pipeline would previously fail:
-
-  audio-dsp mode=merge ! audio-dsp mode=convert ! alsa-sink
-old negotiation:     S16LE                   S24_32LE
-new negotiation:     F32LE                   S24_32LE
-
-The link between the audio-dsp nodes has no restriction, so previously
-it would negotiate S16LE, which would then fail to negotiate with alsa-sink
-because fmtconvert does not know how to convert S16LE to S24_32LE directly.
-
-With this change, the middle link negotiates to F32LE, which can be
-converted to anything.
