        [chromium] Add a copy() method to CCDrawQuad and CCSharedQuadState

        https://bugs.webkit.org/show_bug.cgi?id=95374

        Reviewed by NOBODY (OOPS!).

        The ubercomp layer will hold a RenderPass full of DrawQuads, and needs

        to add quads to the current frame in appendQuads(). It will do this by

        copying the quads it has in its RenderPass into the frame's RenderPass.

        These methods allows it to make a clone of its quads.

        Test: CCDrawQuadTest.copySharedQuadState

              CCDrawQuadTest.copyCheckerboardDrawQuad

              CCDrawQuadTest.copyDebugBorderDrawQuad
