Add option to auto generate bindings for external textures

Browse Source 
With this change, the backend sanitizers always run the
MultiplanarExternalTexture transform. If the new option is enabled, it
auto-generates bindings for this transform.

This change also enables this auto-generation for the Tint commandline
application, as well as for the fuzzers.
