There is a crash report from the Windows OS API
where it repro only win10, not a Win11.
Unfortunately, Microsoft can't access the dump file or
hasn't repro internally so we decided to disable the WGC
fallback use in the OS other than Win11 now.
Once the change (support WGC fallback) reaches to Microsoft Edge
and it produce crash report, Edge team will take the
dump file to the Windows OS API owner for Win10 level fix (or
bring the Win11 fix to Win10).

getDisplayMedia capture the view of the screens and windows
in the capture dialog, but the issue is that captured view
of the Youtube somehow is blank. It repros only in certain
circumstances, for example, Canary channel.
If user reinstall the Canary as fresh new, we observed that
it doesn't repro.
Cause:
We aren't sure what's cause of this one yet.
Solution:
We decided to provide fallback WGC capturer when the main
capturer (GDI) shows blank. WGC could show yellow outline
in prior Win11 OS, but yellow outline looks better than
blank.
The blank detector and fallback capturer are what screen capturer
already supported. So, the solution will follow similar
pattern in the window capturer.

This reverts commit 61709a3233174618d5ab46e1ee5847e4b150c7ef.
Reason for revert: Some downstream projects have issues building this
change due to the inclusion of the <windows.graphics.capture.h> header
which is newly available in the Win 10 SDK v10.0.19041.
To get around this issue for now, this change adds an off-by-default
build flag for these files. However, in the future we will want to
toggle this flag on, and the downstream projects will either need to
update their SDK versions or toggle this flag in their WebRTC clone.

This change introduces the design that will allow us to deliver frames
synchronously to callers despite the Windows.Graphics.Capture APIs being
inherently asynchronous.
We achieve this by having WindowCapturerWinWgc create and maintain a
WgcCaptureSession object for each window that it is asked to capture a
frame for. The capture session object will be the class that actually
uses the WGC APIs, and it will store the frames it receives in a frame
pool and deliver them via GetMostRecentFrame.
The next CL will add the necessary functionality to the
WgcCaptureSession class.

This change implements the GetSourceList and SelectSource APIs from the
DesktopCapturer interface for WindowCapturerWinWgc. No functional
changes were made as the WGC capturer is not in use yet.
I refactored the source enumeration functionality out of the GDI
capturer and into the utils file, so both of the capturers can share
the implementation.
This change also renames the window capturers to include Win in the
name, and updates some of the out dated code style.
I've tested these changes by running the related unit tests and
applying them to a Chromium enlistment and testing on
https://webrtc.github.io/samples/src/content/getusermedia/getdisplaymedia/

This change lays the foundation for the new DesktopCapturer
implementation which will use the Windows.Graphics.Capture API.
In line with the other platform specific DesktopCapturer
implementations, I've moved the actual implementations into the win/
subdirectory and repurposed window_capturer_win.cc to instantiate
the most appropriate implementation. This will be where the WebRTC
field trial (or similar mechanism) and Windows version checks will go
when we begin to roll out the new implementation.
I've verified that the existing window capture functionality still works
by dropping these changes into the third_party/webrtc folder of a
Chromium enlistment, going to
https://webrtc.github.io/samples/src/content/getusermedia/getdisplaymedia/
and stepping through this new path under a debugger, and running the
existing WindowCapturerTests.
The next change in this series will begin to add functionality to the
new window_capturer_win_wgc files.

This change avoids inadvertent capture of certain system windows (e.g.
the Start menu, other taskbar menus, and notification toasts) when
capturing a specific window on Windows.
It stops using EnumWindows for detection of overlapping windows, because
this API excludes these system windows from its enumeration. Using
FindWindowEx instead enumerates these windows.
The enumeration logic is refactored somewhat because a callback is no
longer necessary.

Before the CL [1] https://webrtc-review.googlesource.com/c/src/+/144960
the UWP applications could not be captured so they were filtered out.
Another reason of this previous filter was because otherwise some
'ghost windows' are listed too. These 'ghost windows' are prelaunched
UWP apps whose windows are created in a hidden/cloaked state to improve
perceived performance of launching these apps later, see:
[2] https://docs.microsoft.com/en-us/windows/uwp/launch-resume/handle-app-prelaunch
They can be filtered out using the new API merged recently
'webrtc::WindowCaptureHelperWin::IsWindowCloaked, see:
[3] https://webrtc-review.googlesource.com/c/src/+/143980
This patch allows non-cloaked UWP apps to be listed by taking advantage
of CL [3]. So that user can select them with the app window picker and can
then share them thanks to [1].

This change adds logic to WindowCapturerWin to capture overlapping
owned/pop-up windows (e.g. menus, dialogs, tooltips). This makes window
capture behavior more consistent regardless of whether
CroppingWindowCapturerWin is used & its conditions for using crop-from-
screen capture are met (in ShouldUseScreenCapturer). (I.e. regardless
of OS version, window shape / translucency, occlusion by another
potentially top-most window, or whether the capturing app has opted in
to using the cropping capturer).
Owned/pop-up windows associated with the selected window are enumerated
then captured individually, with their contents composited into the
final frame.
This change also:
- Crops out the top window border (which exposed a bit of the background
when using the cropping capturer, and resulted in an inconsistent
appearance compared to the side & bottom borders being cropped out).

On Win8.1 and Win10 when the window is occluded the cropping capturer
falls back to the PrintWindow API. But without a special flag it
fails when trying to capture apps that are using DirectComposition.
So just pass this undocumented flag named PW_RENDERFULLCONTENT to fix
the fallback case of the cropping capturer.
Due to new app framing on Win8 and Win10 the shadow of the window
are captured as black like if for the maximize case on Win7. So
just use the utility function webrtc::GetCroppedWindowRect and
remove the local GetWindowDrawableRect helper. The former returns
the same result as the later on Win7 so no real change is made here,
just that we make the WindowCapturerWin compatible with newer Windows.

This is a following up cl to the fix of crbug.com/911110. On Windows,
if an App window is suspended, it will block some queries (which
causes Chromium freezing and is fixed in Chromium.) and won't be captured.
So there is no reason to list it in the window capture picker.
Notes: this cl can't fix the case that the select app window becomes
non-responsive just before capturing starts. Hope that an extreme corner
case that can be safely ingored.

Since Windows 10, Windows starts to support virtual desktops. The
problem is when one virtual desktop is not the current one, we can still
enumerate the windows on it, which are still marked as visible by OS.
This causes troubles to decide if a window is on top to be cropped out.
This cl is to utilize a COM API, IsWindowOnCurrentVirtualDesktop of
VirtualDesktopManager, to make sure only the windows on current desktop
will be enumerated.
