This feature is aimed to allow OS make use of the HII database

Export the configuration data and contents of HiiDatabase when
driver add package, update package and remove package.
For string and image may also need to update the contents of
HiiDatabase when NewString/SetString, NewImage/SetImage.

Please make this behavior selectable via a PCD. HII operations are very
expensive, especially on simulators. I don't want to pay the export
time every time a package is added or string is changed. Also,
platforms should be able to decide if they want to offer this data to
the OS.
Why not just export the data once, using a "ready to boot" event hook?
Thanks,
