tst_screencapturebackend: Begin running on macOS in CI

Currently the entirety of tst_screencapturebackend is blacklisted for
macOS in CI. This patch begins enabling by blacklisting only the cases
that are problematic. Some of these test cases are problematic due to
how macOS will often only output new frames when the content is
actually changed. Additionally, some tests are problematic because they
assume the video stream will match the screens refresh rate, which is
usually not true when dealing variable refresh rate displays.

FFmpeg, Windows: Catch exception in GraphicsCaptureSession::IsSupported

QFFmpegWindowCaptureUwp::isSupported() called the WinRT API
GraphicsCaptureSession::IsSupported() directly. Although it is
documented to return a bool, in practice it can throw on systems
without a fully capable Windows Graphics Capture stack. This was
observed when running the tst_qwindowcapturebackend test on a headless
Windows session on CI VMs.

This patch wraps the API all in a try-handler.

tst_qscreencapturebackend: Fix ordering of function definitions

The order in which our test cases are declared does not match the order
in which they are defined. This makes it harder to keep track of the
functions when maintaining it. This patch fixes the ordering.

No functional changes.
