Bring up more tests, and enable zerocopy GL interop in EGL

Bug: 171711491

TODO: BGRA/RGBA format mix is not supported in NVIDIA EGL
(This only has implications for Fuchsia; the hope would be to move
to a 100% Vulkan swapchain by then)

Add more OpenglRender tests
Add snapshot tests
Add Vulkan test

Also, it turns out that NVIDIA EGL does support GL_EXT_memory_objects
now, except that we needed to use eglGetProcAddress to access it.
