backend/drm: stop using GBM flags
gbm_bo_create_with_modifiers doesn't take GBM flags, so our wlr_gbm_allocator interface doesn't either. We were still internally using GBM flags in the DRM backend, leading to awkward back-and-forth conversions. The only flag passed to drm_plane_init_surface was GBM_BO_USE_LINEAR, so turn that into a bool to make sure other flags can't be passed in. Move the "force linear" logic out of init_drm_surface, because the supplied wlr_drm_format should already contain that information.
