Revert of Add functions to support NV_path_rendering in OpenGL ES (https://codereview.chromium.org/345723002/)

Reason for revert:
Will have to unfortunately revert this CL in order to revert https://codereview.chromium.org/319043005/

Original issue's description:
> Add functions to support NV_path_rendering in OpenGL ES
>
> Add OpenGL ES extension functions needed to support NV_path_rendering in OpenGL
> ES.
>
> The added glProgramPathFragmentInputGenNV call is defined in NV_path_rendering
> revision 30, similar to following:
>
>     Append to the end of the "Shader Inputs" subsection of Section 3.12.2
>     "Shader Execution":
>
>     The command
>
>         void ProgramPathFragmentInputGenNV(uint program,
>                                            int location,
>                                            enum genMode,
>                                            int components,
>                                            const float *coeffs);

>     GLSL program object is computed for fragment shading operations that
>     occur as a result of CoverFillPathNV or CoverStrokePathNV.
>
>     /program/ names a GLSL program object.  If /program/ has not been
>     successfully linked, the error INVALID_OPERATION is generated.

>     The given fragment input generation state is loaded into the fragment
>     input variable location identified by /location/.  This location
>     is a value returned either by GetProgramResourceLocation with a
>     /programInterface/ of FRAGMENT_INPUT_NV and a given fragment shader
>     input variable name or by GetProgramResourceiv with FRAGMENT_INPUT_NV
>     for the /programInterface/ and LOCATION for the property for a given
>     fragment input resource index.
>
>     ....
>
> glProgramPathFragmentInputGenNV will be used instead of glPathTexGen,
> because the latter depends on fixed function pipeline that is not
> exposed in ES.
>
> Also add glGetProgramResourceLocation from OpenGL 4.3 or
> ARB_program_interface_query.
>
> Also add FRAGMENT_INPUT define to be used with glGetProgramResourceLocation.
>
> The added functions are not used yet, but they're needed when implementing
> NV_path_rendering support for OpenGL ES. They can also be used on OpenGL.
>
> Remove uncalled NV_path_rendering functions, so they do not cause confusion
> or take space in the interface definition. The ones that are later used
> can be re-added when needed.
>
> Remove definitions NV_path_rendering that are for NV_path_rendering function
> parameters that are not used. The ones that are later used
> can be re-added when needed.
