Currently, the macro type and the "is an ini" value information are
clubbed to together in the cfg component. This lead to not being able to
use the macro type with non-ini configuration values. Split macro type
and "is an ini" value information in the cfg component so that
cfg_in_range can be used with non-ini configuration values.
