Sergey Minakov bfc005d462 iOS: Vulkan support
Implemented Vulkan Support.
Use DisplayServer for rendering and input handling
Use single view for rendering in both GLES2 (not supported yet) and Vulkan
Use @available checks where it's required (otherwise compiler would fail compilation)
Simulator checks
