Revert of Windows video capture: Remove duplicated code from GetDeviceSupportedFormats* (patchset #3 id:200001 of https://codereview.chromium.org/558503003/)

Reason for revert:
See https://code.google.com/p/chromium/issues/detail?id=428958

Original issue's description:
> Windows video capture: Remove duplicated code from GetDeviceSupportedFormats*
>
> The code for GetDeviceSupportedFormatsMediaFoundation and GetDeviceSupportedFormatsDirectShow are already implemented in video_capture_device_mf_win.cc and video_capture_device_win.cc respectively. This CL refactors the implementation so that video_capture_device_factory_win.cc can make use of that code.
