Add non-interop Vulkan functor

An interop Vulkan functor already exists. It will call the OpenGL
functor and use AHardwareBuffer to translate the OpenGL textures into
something which can be used in Vulkan.

This CL adds the frameworks for a non-interop Vulkan functor. This
functor is not yet complete (and as a result cannot yet be tested). This
is just setting the stage for future work.

Test: This is dead code and cannot yet be tested.
