Improve UX of Visual Style Editor for WFS/Vector layers

[allyoucanmap]

Description

There are some fields inside the visual style editor available for 2D but not for 3D and vice-versa. The current solution is to hide the field not available in a specific 2D/3D viewer but it's confusing for user that are not able to find those properties. We should instead keep them visible with a disabled state.

An example of current state

This could be a possible solution (we could think on something better while developing)

Also the symbolizer not available (eg: 3D model) should be disabled but visible

All symbolizer should be reviewed
