Created basalt::context class and its implementation. Creates an underlying VkInstance, and if debug layers are present, creates a VkDebugUtilsMessengerEXT. There are two flags, should_free that controls whether the destructor will do anything, and using_validation_layers that states whether validation layers and debug utils have been setup. This is primarilly done to free them later and signify a runtime debug configuration.
