Clarify how to convert PrimitiveMesh to ArrayMesh.

It took me a bit to figure this out, as I was initially doing something
more complicated like this before I realized I just had to pass
get_mesh_arrays directly to add_surface_from_arrays.

```
var arr_mesh = ArrayMesh.new()
var arrays = []
arrays.resize(ArrayMesh.ARRAY_MAX)
arrays[ArrayMesh.ARRAY_VERTEX] = c.get_mesh_arrays()
arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, arrays)
```

Returns mesh arrays used to constitute surface of [Mesh]. Mesh arrays can be used with [ArrayMesh] to create new surfaces. Returns mesh arrays used to constitute surface of [Mesh]. The result can be passed to [method ArrayMesh.add_surface_from_arrays] to create a new surface. For example:
[codeblock]
var c := CylinderMesh.new()
var arr_mesh := ArrayMesh.new()
arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, c.get_mesh_arrays())
[/codeblock]
