Base class for Geometry and BufferGeometry with common properties

[trusktr]

Create base class for Geometry and BufferGeometry, inheriting from EventDispatcher. Move id, uuid, name, type to the base class.

This might be applicable to any other classes that also have fields like id, type, name, etc.

We don't necessarily need this for the demo. Removing it from the initial port project. We can make improvements later.
