vk_graphics_pipeline: Initial implementation
This abstractio represents the state of the 3D engine at a given draw. Instead of changing individual bits of the pipeline how it's done in APIs like D3D11, OpenGL and NVN; on Vulkan we are forced to put everything together into a single, immutable object. It takes advantage of the few dynamic states Vulkan offers.
