mfenc: Fix building with clang in MSVC mode

that MSVC doesn't complain about, but Clang does. Thus add a missing
header to the custom hacky include path (required for keeping
ICodecAPI visible when building in UWP mode, as it is intended to).

The issue in Windows SDK headers about ICodecAPI availability in
UWP/app mode has been reported upstream at
and later also filed in Feedback Hub (which can't be linked to
