eglfs/kms: Add DRM atomic ModeSetting

This patch will allow to set the video mode with DRM atomic API when available.

Using Atomic ModeSetting will allow further to enable framebuffer upscaling which is
something not possible with DRM legacy API or at least not supported on all devices
in a reliable way.
