Only allow finite numbers in Range.value.

Fixes #81057.

Since this property represents a number in a range, it doesn't make sense for it to be inf or nan.

Bugsquad edit: Fixes #80755

LGTM

Does this solve #80755 for manually edited values in the files? Otherwise I think a dedicated fix is required, including if broken past versions exist

By manually editing you can make the scene completely unopenable in the editor, so I don't think it's a concern. We should only make sure that the data saved by the editor itself is valid.
Also #80755 is difficult to break something by accident. I only opened the issue because I was testing a PR that made it easier to trigger. We also didn't get other reports of broken scenes by using inputting invalid numbers.

To be clear about what I said there, I've only broken my scenes before because I was goofing around and seeing how much I can break Godoh - not intentionally.

This caused a regression in the editor, which uses Range as the base class for editor inspector properties. In the editor inspector, it is expected to display values correctly. Right now, it displays infinity and NaN as 0.0. #88006
