* Revert "Remove GetExternalViewEmbedder from surface (#22272)"
This reverts commit 5419f70f173db1c9f2d5db4c289560e68ce9b77b.
* Revert "Rasterizer is initialized with an external view embedder (#22405)"
This reverts commit f95df42e6e3d80f17c2024e9956768be9416717f.
This is part of a larger effort to expose the difference between GrDirectContext,
which runs on the GPU thread and can directly perform operations like uploading
textures, and GrRecordingContext, which can only queue up work to be delivered
to the GrDirectContext later.
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.
