A grob object is not as much _in_ a given context but announced _from_ a
context.  grob-acknowledgers of an engraver receive their own engraver
as one argument and the source engraver as another.  Checking the
ly:translator-context of the source engraver should give you the closest
you can get to what you want.  Short of what grob-acknowledgers get to
see, there is no record what context a grob originated from.
