These enums are unrelated to nodes. The fact that nodes reuse the
enum property items is an implementation detail that shouldn't leak.
Currently it causes the type dropdown in the "Add Attribute" operator
to be full of node socket icons.
At a data level it is also not clear that these should have node socket
colors, even in geometry nodes. Arguably it's important to distinguish
between attribute types and socket types, especially since some
attribute types cannot be explicitly passed around by node links.
For now, revert the parts of that commit that added node socket icons
in areas unrelated to the node editor. If we're going to do that it needs
proper consensus and a more complete design.
