autotools: wire the new generator for es1 and es2

autotools: wire the new generator for es1 and es2

The output produced functionally identical, with the following changes:
 - A cosmetic: swapped ABI compatible types [ GLclampf -> GLfloat, etc ]
 - B cosmetic: renamed parameters [ zNear -> n, etc ]
 - C dropped extension entrypoints - invalid/incorrect

To make things easier to validate, normalise both old/new headers run
the sed patterns A, B and C to both sets.

v2:
 - gl_dispatch_stub declarations are addressed with previous patch
 - the public_entries table is no longer generated
