Zijie He 74544f9d1b Return translated position in MouseCursorMonitor
This change returns translated position in the newly added overload
MouseCursorMonitor::Callback::OnMouseCursorPosition(DesktopVector) callback.

Meanwhile it also reduces the duplicate logic in Windows capturer
implementations. So except for the deprecated logic in MouseCursorMonitorWin,
all GetSystemMetrics() function calls are merged into GetScreenRect(),
GetFullscreenRect() and GetFullscreenTopLeft() functions.
