"Clear all points" button in Polyline/Polygon and similar components

When working with components that can use a large number of points, clearing the points' list can get tedious since points have to be selected one by one for deletion.

Having a button at the top or bottom of the list to clear it all would ease up that pain!

I guess it would also help to have Delete key presses delete the currently selected point (instead of having to scroll down to click the "-" button) and/or to be able to select multiple points for deletion with Shift. But I figure these two suggestions may be more on Unity's side of things than Shapes'!

Have a nice day ✨
