Adds a new visitor pattern API for creation of visitors which visit all the style entities (symbols, color ramps, text formats, and label styles) associated with different objects. Can be used on a renderer, map layer, or project wide level. E.g. on a project wide level, allows collection of ALL the style symbols/color ramps/text settings inside a project, including those in layouts or annotations!
