Remove hack skipping comparison of algebraic universes in subtyping.
When inferring [u <= v+k] I replaced the exception and instead add
[u <= v]. This is trivially sound and it doesn't seem possible to have
the one without the other (except specially for [Set <= v+k] which was
already handled).
I don't know an example where this used to fail and now succeeds (the
point was to remove an anomaly, but the example
~~~
Module Type SG. Definition DG := Type. End SG.
Module MG : SG. Definition DG := Type : Type. Fail End MG.
~~~
now fails with universe inconsistency.
Fix #7695 (soundness bug!).
