glapi: use gl_and_es_API.xml to generate GLES headers

glapi/gen-es/ defines two sets of GLAPI XMLs for OpenGL ES 1.1
(es1_API.xml) and 2.0 (es2_API.xml) respectively.  They are used to
generate dispatch.h and remap_helper.h for GLES.  Together with
gl_and_es_API.xml, we have to maintain three sets of GLAPI XMLs.

This commit makes dispatch.h and remap_helper.h for GLES be generated
from gl_and_es_API.xml.
