Use mkNakedFunTy in tcPatSynSigwip/T22516
As #22521 showed, in tcPatSynSig we make a "fake type" to
kind-generalise; and that type has unzonked type variables in it. So
we must not use `mkFunTy` (which checks FunTy's invariants) via
`mkPhiTy` when building this type. Instead we need to use
`mkNakedFunTy`.
Easy fix.
