util/gl: Kill shader wrapper functions

This patch kills the wrapper functions defined in piglit-shader.h for GL.
They are rendered obsolete by piglit-dispatch.

A subset of the wrappers are kept for GLES1 and GLES2.

    - All GLES1 wrappers are kept and are renamed to match the core GL
      names.  That is, piglit_$func is renamed to gl$func. As before, the
      wrappers simply raise an assertion failure because GLES1 does not
      suppport shaders.

    - The subset of GLES2 wrappers that raise an assertion, because the
      function is not supported on GLES2,  are also kept and likewise
      renamed.
