745a73eece wasapi2: Don't use global volume control object
ISimpleAudioVolume controls volume of corresponding audio session
and there would be only single input/output audio session
in case of share-mode, which means that it controls audio volume of the
process. Instead, use IAudioStreamVolume interface which controls
volume of the stream.

ae04702d23 wasapi2: Use C++ atomic instead of GLib

c992dd2184 wasapi2ringbuffer: Don't use GLib's weak pointer implementation
GWeakRef takes global mutex. Use C++ weak_ptr which will perform
atomic operation internally.

07cf7b2a29 wasapi2: Add option to monitor loopback device's mute state
When loopback recording from a render device, the wasapi2src element
captures audio even if the device is muted. This change adds the
'loopback-silence-on-device-mute' property that, when set to `true`,
causes wasapi2src to inject silence in the pipeline when
the device is muted.

cb7958e710 wasapi2: Add support for process loopback capture
Adding loopback capture mode for specified PID.

Note that this feature requires Windows 10 build 20348
(Windows 11/Windows Server 2022 or later),
and any process loopback related properties will not be exposed
if OS does not support it.

Example launch lines:
* wasapi2src loopback-mode=include-process-tree loopback-target-pid=<PID>
 Captures audio generated by an application (specified by PID)
 and its child process
* wasapi2src loopback-mode=exclude-process-tree loopback-target-pid=<PID>
 Captures desktop audio excluding PID and its child process

009bc15f33 wasapi2ringbuffer: Fix for desynced buffer-size and segsize
GstAudioRingBufferSpec::segsize has been configured by using
device period but GstWasapi2RingBuffer was referencing the
buffer size returned by IAudioClient::GetBufferSize()
which is most likely larger than device period.
Fixing to sync them.
