This also fixes an issue where eglChooseConfig was only being called in InitializeOneOff, which is only called once per process. This CL makes choosing the config happen once per GLSurface instead, which will ultimately permit apps to create multiple native_viewports with different surface configurations on the same display. The eglDisplay object is still a global, though. R=abarth@chromium.org, viettrungluu@chromium.org, jamesr@chromium.org Review URL: https://codereview.chromium.org/1168993002.
