Add may_contain_cursor property to DesktopFrame to avoid double capture

This CL adds a new property to the DesktopFrame interface to indicate
that the capturer supports cursor capture and the frame may contain
an image of the cursor (if the cursor was over the window or screen
being captured). This allows the DesktopAndCursorComposer to avoid
compositing another image of the cursor on the frame.

This is preferred because natively capturing the cursor will likely
be more efficient, and for WGC the API to disable cursor capture
is only availabe on later versions of Win10, reducing the number
of users that could use it.
