Construct in_scope set in mkTopTCvSubst
The pre-condition on `mkTopTCvSubst` turned out to be wrong and
not satisfied by any of the callers. I've fixed it, so that it
constructs the in_scope set from the range of the substitution.
`mkTopTCvSubst` was also unnecessarily general it is never called
with `CoVars`, so I changed the type signature and added an assertion.
