Clean up Class::GetDirectInterface().

Fetch array interfaces from the `IfTable`. This removes the
only use of the `Thread* self` argument, so we can remove
that argument. We also make the function non-static to avoid
the explicit `klass` argument. Similarly clean up arguments
of `Class::FindClass()` and `Class::FindStaticClass()`.
