Fix #13983 by creating a TyConFlavour type, and using it
An error message was referring to a type synonym as a datatype.
Annoyingly, learning that the TyCon over which the error message is
operating is actually a type synonym was previously impossible, since
that code only had access to a TcTyCon, which doesn't retain any
information about what sort of TyCon it is.
To rectify this, I created a new TyConFlavour datatype, intended to
capture roughly what sort of TyCon we're dealing with. I then performing
the necessary plumbing to ensure all TcTyCons have a TyConFlavour, and
propagated this information through to the relevant error message.
