We can merge VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES with VDPA_ATTR_DEV_FEATURES which is functionally equivalent. While at it, tweak the comment in header file to make user provioned device features distinguished from those supported by the parent mgmtdev device: the former of which can be inherited as a whole from the latter, or can be a subset of the latter if explicitly specified.
