Doc: Correct declared eigen version

Commit eeab35c547c575e5ccb34523ca97cef25dcea596 set the version
to 5.1.0. However, the latest eigen version is 5.0.1, and that
is also what is declared in the commit and the download location.

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_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.

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.

Darwin: unify display link implementations across Apple platforms

CVDisplayLink is deprecated in macOS 15.0. The replacement APIs
(NSView, NSWindow, NSScreen displayLink) return CADisplayLink,
the same class iOS has always used.

Unify macOS and iOS under a single CADisplayLink-backed
DisplayLinkObserver, using the screen-specific creation API
on macOS 15+ while keeping CVDisplayLink as a fallback for
older releases.
