This reverts back to the old way of extending the vertex format with the necessary vertex element for lightmap data, if fullbright quads are enabled. Instead of then enabling the extended vertex format for Optifine, it is disabled if Optifine is detected.

Since the root cause is actually that the Vanilla lighting pipeline doesn't support such Vertex Formats, we disable it also if the Forge lighting pipeline is disabled.

This also relates to #2489.
