Revert "Make GPU backend triangulate rects such that they are rendered as tri strips rather than tri fans."

This reverts commit fa2d604a7d.

Reason for revert: <INSERT REASONING HERE>

Original change's description:
> Make GPU backend triangulate rects such that they are rendered as tri strips rather than tri fans.
> 
> Right now when we turn rects into quads we use a vertex order compatible with a tri fan rather than a tri strip.
> 
> I wanted it to be the case that the same code could be used to generate a non-indexed mesh for a single rect or indexed using the quad index buffer when batching. Triangle fanning is not available in all APIS (e.g. is emulated in ANGLE and not supported in Metal) so it seems better to use a triangle strip over a fan in the single rect case.
