PipeWire capturer: add initial test for SharedScreenCastStream

This test created another PipeWire stream we can connect to with
SharedScreenCastStream and recieve frames from there. This is an
initial version, where I test whether we can successfuly connect
and disconnect, receive frames and it also tests DesktopFrameQueue.

In the future I will add tests to test mouse cursor and try to
come up with some corner cases and possible scenarios.
