conf: Introduce pipewire audio backend

QEMU gained support for PipeWire audio backend (see QEMU commit of v8.0.0-403-gc2d3d1c294). Its configuration knobs are basically the same as pulseaudio's, except for PA's server name. Therefore, a lot of code is copied over from pulseadio and fixed by s/Pulse/Pipewire/ or s/pulseaudio/pipewire/. There's one ley difference to PA though: pipewire daemon is usually on per user basis (just like our qemu:///session). Therefore, introduce this 'runtimeDir' attribute, which allows specifying path to pipewire daemon socket (useful for qemu:///system for instance).

+PipeWire audio backend
+^^^^^^^^^^^^^^^^^^^^^^
+
+The ``pipewire`` audio backend delegates to a PipeWire daemon audio input and
+output.
+
+The following additional attributes are permitted on the ``<input/>`` and
+``<output/>`` elements:
+
+* ``name``
+
+  The sink/source name to use
+
+* ``streamName``
+
+  The name to identify the stream associated with the VM
+
+* ``latency``
+
+  Desired latency for the server to target in microseconds
+
+::
+
+   <audio id="1" type="pipewire">
+     <input name="fish" streamName="food" latency="100"/>
+     <output name="fish" streamName="food" latency="200"/>
+   </audio>
+
+Optionally, path to pipewire daemon socket (aka ``PIPEWIRE_RUNTIME_DIR``) can
+be specified via ``runtimeDir`` attribute. This is useful when a domain under
+``qemu:///system`` wants to use session pipewire daemon, or vice versa.
+
+::
+
+   <audio id="1" type="pipewire" runtimeDir='/run/user/1000'>
+     <input name="fish" streamName="food" latency="100"/>
+     <output name="fish" streamName="food" latency="200"/>
