glsl: add helper to process xfb qualifiers during linking

This function checks for any xfb_* qualifiers which will enable
transform feedback mode and cause any API defined xfb varyings
to be ignored.

It also counts the number of varyings that have a xfb_offset
qualifier and finally it calls the create_xfb_varying_names()
helper to generate the names of varyings to be caputured.
