In this patch we populate the form with the two widgets related to video resolution: - A read-only string field displaying the preference for the next boot. - A drop-down list offering choices for changing the setting. This list is implemented with dynamically generated IFR opcodes. (In general, the current preference may be missing, or it may be invalid for the available video RAM size. The list of possible new settings is filtered with the video RAM size.) Because the form now becomes able to receive input, we must also implement ExtractConfig(). This function tells the HII engine about the state of the widgets. For now we set up both widgets with static data only: - The current preference always says "Unset". The driver code is still isolated from the backend (the UEFI variable store). - The list of possible resolutions offers 800x600 only. We don't interrogate the GOP yet.
