benchmarks/glmark2: update the port to version 2023.01

• Now uses the Meson build system for the most common build flavors (X11, Wayland, DRM)
• Add new option for GBM offscreen rendering (not sure how useful it is though)
• Move gl' and localbase' from global USES to those options which actually require them
