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).
