`FloatHint::Enum` might not be valid

[chitoyuu]

There has been a report on Discord that FloatHint::Enum doesn't work ("the godot editor doesn't show a drop down list on the resource"). There seems to be no equivalent GDScript examples in the official docs, and the hint itself doesn't seem to make much intuitive sense. It's suspected that the FloatHint::Enum variant might be the result of a copy-paste mistake, and was never supported by the editor in the first place.

We should look into the relevant parts of engine code and determine if that was the case.

If it's currently not working and we don't see an obvious fix, I would say we remove it for 0.10.0 (as we can't have breaking changes afterwards).

Or has someone already had the chance to look deeper into this?

No, I don't think anyone has looked properly into it yet. We can remove it for 0.10.0, and maybe add it back later if something turns out to make it work.
