- removed gl_render_subsectors test CVAR and disabled vertex buffer generation for legacy mode

Browse source 
To reduce the performance impact, legacy mode will now always create flat vertex data on the fly instead of relying on the vertex buffer. This makes the CVAR mostly redundant as on anything more modern rendering per subsector will always be slower.
