[shell tests] Integrate Vulkan with Shell Tests
This change creates a test only implementation of flutter::Surface backed by an offscreen Vulkan GrContext. Much of the code in this test Surface was lifted from flutter::VulkanWindow which I was unable to use without extricating it from the VkSurface/VkSwapchain code which we do not want to use in offscreen tests. I would recommend refactoring VulkanWindow to separate GrContext creation and VkSwapchain creation in order to promote greater code reuse between onscreen and offscreen vulkan paths. This change is excersised thoroughly by the shell tests and was manually tested against these tests on Fuchsia on Intel.
