Thanks to Amin Timany for the suggestion.

Add both nonexpansive and contractive functors, and bundle them for the general Iris instance as well as the global functor construction This allows us to move the \later in the userdefined functor to any place we want. In particular, we can now have "\later (iProp > iProp)" in the ghost CMRA.

This cleans up some adhoc stuff and prepares for a generalization of saved propositions.

And now the part that I forgot to commit.

Also, give all these global functors the suffix GF to avoid shadowing such as we had with authF. And add some type annotations for clarity.

The non applied one should be only parsing.

I added a new typeclass "inGF" to witness that a particular *functor* is part of \Sigma. inG, in contrast, witnesses a particular *CMRA* to be in there, after applying the functor to "\later iProp". inGF can be inferred if that functor is consed to the head of \Sigma, and it is preserved by consing a new functor to \Sigma. This is not the case for inG since the recursive occurence of \Sigma also changes. For evry construction (auth, sts, saved_prop), there is an instance infering the respective authG, stsG, savedPropG from an inGF. There is also a global inG_inGF, but Coq is unable to use it. I tried to instead have *only* inGF, since having both typeclasses seemed weird. However, then the actual type that e.g. "own" is about is the result of applying a functor, and Coq entirely fails to infer anything. I had to add a few type annotations in heap.v, because Coq tried to use the "authG_inGF" instance before the A got fixed, and ended up looping and expanding endlessly on that proof of timelessness. This does not seem entirely unreasonable, I was honestly surprised Coq was able to infer the types previously.
