LUCENE-8746: Refactor EdgeTree (#878)
Introduce a Component tree that represents the tree of components (e.g polygons).
Edge tree is now just a tree of edges.

> Currently the class {{EdgeTree}} is a bit confusing as it is in reality a tree of components. The inner class {{Edge}} is the one that builds a tree of edges which is used by Polygon2D and Line2D to represent their structure.
> Here is proposed:
> 1) Create a new class called {{ComponentTree}} which is in fact the current {{EdgeTree}}
> 2) Modify {{EdgeTree}} to be in fact the inner class Edge
> 3) Extract a {{Component}} interface so we can have different types of components in the same tree. This allow us to support heterogeneous trees of components.
> 4) Make {{Polygon2D}} and {{Line2D}} instance of the component interface.
> 4) With this change, {{LatLonShapePolygonQuery}} and {{LatLonShapeLineQuery}} can be replaced with one {{LatLonShapeComponentQuery.}}
