The DXGI_OUTDUPL_FRAME_INFO type isn't available in Windows API

This fixes compilation for UWP/"Windows Store" configurations (and
older API subsets like Windows Phone).
The entire desktop duplication API is not present on Phone targets
(its called "desktop" duplication afterall). I think it would be
better to check for a primary DDA function, instead of some auxiliary
structure.
FWIW, based on the MSVC error output
(http://fate.ffmpeg.org/log.cgi?log=compile&slot=arm-msvc2019-phone&time=20220730152801),
the only hard errors it listed were the undefined types
(DXGI_OUTDUPL_POINTER_SHAPE_INFO and DXGI_OUTDUPL_FRAME_INFO) - but I
presume that IDXGIOutputDuplication_AcquireNextFrame and
IDXGIOutputDuplication_ReleaseFrame could be good candidates for checking
too - I don't see anything else in that error log that one could check
for?
