Move node type to visualization container

[kazcw]

Pull Request Description

node-types.mov

• When a visualization is shown, the node's type name is displayed, unqualified, at the right end of the visualization toolbar.
• When the unqualified type name is hovered, a tooltip shows the full type name.
• Hovering output ports no longer shows a type name.

Closes #9416.

Important Notes

Refinement note: Take care if the custom vis icons won't obscure the type label.

The node type is a child of the same flexbox as the custom toolbar, so there shouldn't be any problem.
