Add gles support to egl-helpers, wire up in egl-headless and gtk.

Browse Source 
Add support for OpenGL ES to egl-helpers.  Wire up the new option for
egl-headless and gtk UIs.  egl-headless actually works fine.  gtk hits a
not-yet implemented code path in libEGL when trying to use gles mode:

  libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.

(This is mesa 17.2.3).
