Simplify MultiplanarExternalTexture::ShouldRun. 

Currently the multiplanar `ShouldRun` function is scanning all objects
looking for an external texture. This CL switches to using the type
manager and attempts to find an `ExternalTexture` type in the system. If
found, then the transform should run.
