Fix container minimum size with hidden parent

[anniryynanen]

Fixes #93464.

MRP for testing the changed containers: container-visibility.zip

The minimum size bug can be a bit fickle to reproduce. In the above MRP, if you change the position of a panel by 1 px it stops reproducing until the inner ColorRect's size is reset, the panel's size is reset, and the ColorRect's size is set again.

Graphs and TabContainer use SortableVisbilityMode::IGNORE, I didn't change that as they seem like special cases.

EditorInspector also uses as_sortable_control() in get_minimum_size() for EditorProperty and EditorInspectorSection. I didn't add SortableVisbilityMode::VISIBLE there as I'm not sure if the bug reproduces there, or how I'd go about testing it.

Half of the containers already use VISIBLE mode, so this makes sense.
