Geometry Nodes: Don't allow UI attributes as modifier field inputs

This is an extension of 4669178fc3786e1, applying the same changes to
attributes chosen in the field inputs of the geometry nodes modifier.
If a UI/internal attribute is used, the attribute name button will
have a red alert. Adding a disabled hint is currently a bit more complex.

Also hide UI attributes in attribute search for the named attribute node.
