Description

Issue #12358 introduces a new kind Dataplane, we need to add matching support:

• labels work the same way as to[].targetRef.kind: MeshService
• name/namespace fields allow to reference the real Dataplane resource

Don't support in this issue:

• sectionName, it should be implemented later when we rewrite the inbound policies to use rules instead of from.

Make sure that by using kuma.io/proxy-type it's possible to replace targetRef.proxyTypes field. Probably by creating a set of unit tests.
