vdpa: merge functionally duplicated dev_features attributes
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.
