Move OpenGL ES 2.0 conformance test support into main tree

Move OpenGL ES 2.0 conformance test support into main tree

This support breaks often because it is not built but the buildbots.
This CL adds it to the main tree so it will be built by the buildbots.

Not sure where to add it in all.gyp but I need to make sure it's built

TEST=opengl es 2.0 conformance tests still build

I have a CL for the actual OpenGL ES 2.0 conformance tests
that use this CL. Once it's in I'll check that in.
