cogl: Just define the needed GLES2 extension ourself

Browse Source 
We need a GLES2 extension macro in cogl-texture-2d-gl.c, but we can't
include GLES2/gl2ext.h because it will conflict with things in
GL/glext.h. We can't rely on cogl including anything for us since it'd
only include GLES2/gl2ext.h if OpenGL support was explicitly disabled.
