chore(aggregations): Refactor aggregations stage toolbar

[kraenhansen]

Description

An alternative to the refactor which happened in #6569 (comment) favoring composition over arrays of props.

I included a change to re-export the GlyphName from LG instead of deriving and exporting our own from the "components" package.

What benefit does it have to pass these two here instead of just onClick and then something like:

	onClick={() => {
        onAddStageClick(index);
        setMenuOpen(false);
    }}

[mabaasit]

not a blocker though.

[kraenhansen]

This just ensures that setMenuOpen(false) is always called when onClick is called on any item.. Not making that a choice of the caller.
