3D polygon shape for use with occlusion culling in [OccluderInstance3D].
[ArrayOccluder3D] stores an arbitrary 3D polygon shape that can be used by the engine's occlusion culling system. This is analogous to [ArrayMesh], but for occluders. See [OccluderInstance3D]'s documentation for instructions on setting up occlusion culling.

Sets [member indices] and [member vertices], while updating the final occluder only once after both values are set.
- The occluder's index position. Indices determine which points from the [member vertices] array should be drawn, and in which order. [b]Note:[/b] The occluder is always updated after setting this value. If creating occluders procedurally, consider using [method set_arrays] instead to avoid updating the occluder twice when it's created.
- The occluder's vertex positions in local 3D coordinates. [b]Note:[/b] The occluder is always updated after setting this value. If creating occluders procedurally, consider using [method set_arrays] instead to avoid updating the occluder twice when it's created.
