gl-renderer: Move EGL client extension handling earlier

EGL client extensions are not tied to the EGLDisplay we create, and have
an effect on how we create the EGLDisplay. Since we're using this to
look for EGL_EXT_platform_base, it makes more sense for this to be near
the start of the GL renderer initialization.
