treat generic body type as atomic in iterOverType (#24096)

follows up #24095

In #24095 a check was added that used `iterOverType` to check if a type
contained unresolved types, with the aim of always treating
`tyGenericBody` as resolved. But the body of the `tyGenericBody` is also
iterated over in `iterOverType`, so if the body of the type actually
used generic parameters (which isn't the case in the test added in
#24095, but is now), the check would still count the type as unresolved.

This is handled by not iterating over the children of `tyGenericBody`,
the only users of `iterOverType` are `containsGenericType` and
`containsUnresolvedType`, the first one always returns true for
`tyGenericBody` and the second one aims to always return false.
Unfortunately this means `iterOverType` isn't as generic of an API
anymore but maybe it shouldn't be used anymore for these procs.
