wasapi2: Add support for format negotiation
...
Enumerate supported formats during open so that src/sink can
report them via get_caps(). The format is then fixated and
initialized on acquire(), allowing users to select their
preferred format

wasapi2: Workaround for S24_32LE format mismatch
...
Since Windows 24bit-in-32bit format is not supported
by GStreamer (Windows one is MSB-aligned), converts format
in ringbuffer using SSE2.

wasapi2: Add support for exclusive mode device switching
...
Because of APO/OS mixer bypass in exclusive mode, we should
convert samples if new device has different format.
The conversion with additional buffering is implemented in this patch

wasapi2: Warm up capture audio client on open
...
If the endpoint is idle, the first IAudioClient::Start() call
may take a long time to return. Start/stop the capture client
on open to reduce latency of subsequent Start() calls.

wasapi2sink: Do not push too large preroll buffer to endpoint
...
To avoid startup glitches, a silent buffer is pushed to
render endpoint, but pushing too large silent buffer will
introduce unnecessary latency. Limit it to a single period worth data.

wasapi2: Add continue-on-error property
...
If enabled, wasapi2src/sink will post a warning message instead of an error,
when device failures occur, such as open failure, I/O error,
or device removal.
The element will continue to produce/consume audio buffers and behave as if
a capture/render device were active, allowing pipeline to keep running even when
no audio endpoint is available
