Create CollisionPolygon2D sibling for Multiple Selected Sprite2Ds

[Sunecraftian]

An idea to extend the current feature to create siblings for multiple selected Sprite2Ds instead of just one at a time.

Open the same preview window, but this time have a list of each selected Sprite2D on the left side (similar to the TileSet/Tile Sources window). You can go through each one and change individual settings, or you may also want to add an "Apply to All" checkbox to apply the settings to selections when working with similarly shaped Sprite2Ds.
