The goal is to be able to build fully custom tooltips for entire layouts (e.g. for all `uiBut` for a socket). We already support tooltip callbacks for layouts and fully custom tooltips for `uiBut`, however not fully custom tooltips for an entire layout. This will be used by #140540. The main noteworthy thing here is that now `uiBut` is passed into the custom tooltip function. This is necessary when the tooltip still has to be customized for the exact hovered `uiBut`. For example, we generate a tooltip that applies to an entire vector socket, but when hovering over e.g. the X input value, the Python tooltip should show the path for that specific property. This also fixes a bug in `ui_but_is_interactive_ex` which didn't consider custom and quick tooltips before. `uiLayoutSetTooltipCustomFunc` is pretty much the same as its non-custom counterpart.
