Revert "mesa, compiler: Move gl_texture_index to glsl_types.h"

This reverts commit 1b836a52ea.  This
patch, while claiming to decouple things, actually increases coupling
because it leaks two OpenGL state tracker limits and an OpenGL state
tracker fixed binding enum into the entire compiler.  Nothing wants to
know these outside the OpenGL state tracker and the GL-specific compiler
passes.  Put them back where they were.
