dawn/opengl: require EGL_EXT_create_context_robustness

Latest SwiftShader roll into Dawn failed because tests like
TriangleStripPrimitiveRestartTests.Uint32WithoutPrimitiveRestart relies
on robustness checks being enabled, but a recent change to SwiftShader
no longer enabled robustness by default. This change makes sure to
enable the robustness extension.
