0f4bddc9a9 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

c97ed1e6f6 wasapi2: Workaround for S24_32LE format mismatch

0d94713288 wasapi2: Demote S24_32LE in exclusive-mode format ordering 
Some endpoints accept 24-bit in 32-bit PCM (S24_32LE) in exclusive mode
but playback at very low volume. Until the root cause is identified,
push S24_32LE to the end of the candidate list

93f0135798 wasapi2: Fix choppy rendering 
This reverts questionable commit 009bc15f3397252e9e3954ae4af15ffcdbdeac69
which looks completely wrong.

The GstWasapi2RingBuffer:buffer_size variable is used to
calculate available buffer size we can write
(i.e., available size = buffer_size - padding_size).
But the commit makes the size to be exactly same as buffer period.
Then, it can confuse this element as if the endpoint buffer is full on
I/O event callback (if padding size is equal to buffer period)
but it's not true.

'loopback-silence-on-device-mute' property that, when set to `true`,
