Changes

Closes #277

• Implement uses_shaders
• Implement push_constant_range template method
• Refactor handling of vertex input attribute descriptions
• Set texture format directly in constructor of TextureResource and remove set_format method
• Make calls to render stage setup chainable
• Add wrapper for VkPipelineLayout
• Add wrapper for graphics pipelines
• Add graphics pipeline builder
• Add wrapper for VkRenderPass (This will go away once we have dynamic rendering)
• Add renderpass builder (Renderpasses will be removed anyways once we support dynamic rendering: Implement support for dynamic rendering #438)
• Add wrapper for VkSampler
• Refactor Image RAII wrapper class and use it in rendergraph
• Remove unused MeshBuffer class
• Remove unused msaa_target.hpp file

Outlook: Refactoring, part 2

• Refactor buffer and descriptor management into rendergraph #526
• Refactor descriptors and descriptor builder so it becomes a part of rendergraph #430
• Implement basic SPIR-V reflection #418
• Don't recompile the entire rendergraph at swapchain recreation #288
• Give each octree its own vertex buffer, index buffer and uniform buffer (This is important for [collision] Add vertex collisions to octree collision detection #423)
• Rendergraph input validation #204
• Modify descriptor builder to allow for multiple images to be passed into the builder pattern. #285
• Multisampling with rendergraph #203
