Introduce per-platform exception mode lists (e.g. nvl_joiner_exception_modes[]) dispatched via novalake check in a new mode_needs_joiner_exception() helper, and wire it into igt_bigjoiner_possible(). Fix intel_boundary_non_joiner_mode_found() to skip exception modes, preventing test_basic_max_non_joiner from incorrectly selecting a joiner-required mode as a non-joiner boundary mode.
