Implement EGL_CreatePlatformWindowSurface() The function EGL_CreatePlatformWindowSurface() was introduced by EGL 1.5 and is required by dEQP starting with 3.2.6. ANGLE has worked around EGL_CreatePlatformWindowSurface() being unimplemented by submitting conformance on 3.2.5, but Android's internal master uses ToT dEQP so we need to implement this to pass CTS and enable SWANGLE on CuttleFish.
