vboot/ui: Add refresh flag to support force refresh the screen in action

CL:2163088 is working on depthcharge side to support refreshing
everything in vboot side, but it is still work in progress.
In the meanwhile, we can have a flag to control the refreshing for
already support refreshing everytime screen.

This flag can be removed after all screens are supported refreshing
everytime in vboot.

BUG=b:156692539, b:156693348
TEST=emerge-hatch vboot_reference
TEST=verfied in later CL that the screen is refreshed when the action
callback set this flag.
