Integrate Multiplanar External Texture Transform

Browse Source 
Introduces the majority of the logic associated with enabling
multiplanar external textures. Removes most backend logic associated
with external textures in favor of expanding them into their components
in the frontend. Includes a basic e2e test demonstrating multiplanar
YUV-to-RGB conversion.
