Several tests starting failing when run on trybots on Win10. This CL
fixes several issues that were uncovered.
Issue 1:
Capture failed to start because `get_Size` returned {0, 0}. This is a
known issue in the WGC API that occurs when there are multiple user
sessions on the same machine.
Solution:
Add a `GetSize` method to the `WgcCaptureSource` interface so we can
fallback to other methods if `get_Size` fails.
Issue 2:
The screen capture tests assume there will be displays attached and
fail if there aren't.
Solution:
Always run `IsWgcSupported` for the appropriate capture type.
Issue 3:
ASAN container-overflow in `GetTestWindowIdFromSourceList`
Solution:
Check the validity of the iterator before dereferencing.
Issue 4:
Occasionally, the call to `GetMessage` in the `CloseWindowMidCapture`
test would hang because there were no messages in the queue.
Solution:
Use `PeekMessage` instead which will return if there are no messages.
