Revert "Wait for frames to arrive in WgcCapturer instead of returning nothing."

This reverts commit 93bb3051490253d56dc1cdab4701b91138a151c3.

Reason for revert: It breaks a test while rolling into Chromium,
see https://webrtc-review.googlesource.com/c/src/+/261780/21#message-4a96e33bfb475f19a618be82bbe72951b23085ef for details.

Original change's description:
> Wait for frames to arrive in WgcCapturer instead of returning nothing.
>
> We're seeing a high instance of "first capture failed" in Chromium when
> using WGC. We can reduce this by waiting for frames to arrive if there
> are none in the frame pool instead of returning a temporary error.
>
> I've set the maximum time to wait for a frame to 50ms. If no frame
> arrives before 50ms has elapsed, we will return a temporary error.
> Added a new test, FirstCaptureSucceeds, to verify that this is working
> as expected.
>
> As part of this I updated the name of the `kCreateFreeThreadedFailed`
> enum value to `kCreateFramePoolFailed`. The value remains the same
> since they both report failures in frame pool creation.
>
> I also increased `kNumBuffers` from 1 to 2, so that the frame pool can
> store two frames. This should prevent us from having to wait on the
> event as frequently. This will increase the latency between capture
> and display, however. High frame rate applications should not be
> noticeably affected.
>
> Additionally, we uncovered a bug in the OS that prevents window capture
> when there are displays attached, but none of them are active. Added
> a new check to `IsWgcSupported` to cover this scenario.
>
> Finally, some issues with other WGC tests blocked moving the TryBots
> to a newer version of Windows. This CL fixes those issues and updates
> the TryBot configuration.
>
> bug: chromium:1314868
