This patch converts all the errors to do with loading interface files
into proper structured diagnostics.

* DriverMessage: Sometimes in the driver we attempt to load an interface
  file so we embed the IfaceMessage into the DriverMessage.
* TcRnMessage: Most the time we are loading interface files during
  typechecking, so we embed the IfaceMessage

This patch also removes the TcRnInterfaceLookupError constructor which
is superceded by the IfaceMessage, which is now structured compared to
just storing an SDoc before.

The function GHC.Tc.Utils.TcType.ltPatersonSize would panic when it
encountered a type family on the RHS, as usually these are not allowed
(type families are not allowed on the RHS of class instances or of
quantified constraints). However, it is possible to still encounter
type families on the RHS after doing a bit of constraint solving, as
seen in test case T23171. This could trigger the panic in the call to
ltPatersonSize in GHC.Tc.Solver.Canonical.mk_strict_superclasses, which
is involved in avoiding loopy superclass constraints.

This patch simply changes ltPatersonSize to return "I don't know, because
there's a type family involved" in these cases.

Fixes #23171
