Vulkan: Use one pipeline layout for all Programs. This simplifies the pipeline state object caching. We will not need to use any extra bits to cache based on program properties - instead all programs will be compatible. The pipeline layout strucutre is described in the design docs. It currently only has two bind groups: the first for default uniforms, and the second for Textures. In the future we might re-organize this to handle driver uniforms, dynamic push constants, and/or program uniform buffers with ES 3.0. Instead of storing only the Textures that are required by a Program, we reserve space for the maximum possible Texture units. We might have to revisit this very simple design in the future to support texture arrays, which are handled specially in Vulkan.
