Make the tyvars in TH-reified data family instances uniform
It turns out we were using two different sets of type variables when
reifying data family instances in Template Haskell. We were using the
tyvars quantifying over the instance itself for the LHS, but using the
tyvars quantifying over the data family instance constructor for the
RHS. This commit uses the instance tyvars for both the LHS and the RHS,
fixing #13618.
Test Plan: make test TEST=T13618
