Fixes anchor rendering (#2698)

* Fixes #2680: Use a shorter cable anchor model when blocked by a facade.
* Fixes #2664: Prevent anchors from creating intersection.

Replaced the simple List<ResourceLocation> for the static models with a
new container also indicating a solid part, which can be used to prevent
the creation of an intersection.
