This PR renames `PartialHomeomorph` to `OpenPartialHomeomorph` as discussed in [#mathlib4 > Generalizing `PartialHomeomorph`?](https://leanprover.zulipchat.com/#narrow/channel/287929-mathlib4/topic/Generalizing.20.60PartialHomeomorph.60.3F). This is the first step towards generalizing `PartialHomeomorph` to allow arbitrary sources and targets.

There are 3 such removals and they are removed for 3 different reasons:
* in `Mathlib/Analysis/Analytic/Within.lean`, there are several active goals, so we use the focusing dots;
* in `Mathlib/Analysis/CStarAlgebra/ApproximateUnit.lean`, the linter does not actually flag an issue;
* in `Mathlib/Probability/Kernel/Proper.lean`, the *infoview* hides a goal in the presence of `simp_rw`, but the goal is there ([#mathlib4 > `simp_rw` hides a goal @ 💬](https://leanprover.zulipchat.com/#narrow/channel/287929-mathlib4/topic/.60simp_rw.60.20hides.20a.20goal/near/564013486)).
