Feature/vulkan first render (#545)

* First pass at InputLayout for Vulkan
Add support for RGBA_Float32

* Use VulkanModule and VulkanApi to handle accessing Vulkan types.

* First pass at Vulkan swap chain/Device queue.

* Added VulkanUtil for generic function functions.

* Move more functionality to VulkanApi and VulkanUtil.
Make Buffer able to initialize itself.

* More tidy up around VulkanDeviceQueue

* First pass use of VulkanDeviceQueue in VkRenderer

* First pass use of VulkanSwapChain on VkRenderer

* Added depth formats.
Binding for constant and vertex buffers for Vulkan.

* Setting up VkImageView on backbuffers.

* First pass support for setting up vkRenderPass.

* Fixes to work around Vulkan swap chain/verification issues.

* Added support for Pipeline and a pipeline cache.

* Working without waiting - because use of pipeline cache.

* Added support for VkFramebuffer in Vulkan.

* First pass at creating Vulkan graphics pipeline.

* More efforts to get Vulkan to render.

* Small improvement for checking of Binding flags.

* Removed setConstantBuffers from the Renderer interface - so that all resource binding takes place through the BindingState.
To make this work required a 'hack' in render-test main.cpp - so that the constant buffer binding that is needed in some tests is only added when it doesn't clash.

* RendererID -> unified into RendererType. Added getRendererType to Renderer interface.
Added ProjectionStyle, and function to get from RendererType.
Added getIdentityProjection to RendererUtil - to get projection that is the 'identity' - but hits the same pixels for all projection styles.

* Fix build problem on Win32 on Vulkan where should use VK_NULL_HANDLE.

* Improve naming, comments. Remove dead code.

* Remove unwanted comment.
