Fetch anchors that support a given set of component types.
Each anchor supports one or more anchor types (types that implemented IOVRAnchorComponent<T>).If not null, ComponentTypes must be a collection of types that implement IOVRAnchorComponent<T>, e.g.,
OVRBounded2D or
OVRRoomLayout.When multiple components are specified, all anchors that support any of those types are returned, i.e., the component types are OR'd together to determine whether an anchor matches.If you only have a single component type, you can use SingleComponentType to avoid having to create a temporary container of length one.
