Nyall Dawson d464f86290 [FEATURE] Null ("No symbol") renderer
Using this renderer no symbol will be drawn for features, but labeling,
diagrams and other non-symbol parts will still be shown.

Selections can still be made on the layer in the canvas and selected
features will be rendered with a default symbol. Features being edited
will also be shown.

This is intended as a handy shortcut for layers which you only want
to show labels or diagrams for, and avoids the need to render
symbols with totally transparent fill/border to achieve this.

(fix #12131)
