[Piglit] [PATCH] gl-2.0: port const vertex attrib webgl test to piglit

This is a rip off of:
https://www.khronos.org/registry/webgl/conformance-suites/1.0.2/conformance/attribs/gl-vertex-attrib-render.html
Which presently fails with gallium drivers. The logic is identical, just
ported to GL and piglit infra.
