Change subject: Support for creating hybrid vboot images

Support for creating hybrid vboot images

This allows creating an image where RO is triggered by default with
normal RW secrets locked out. On a signal in CMOS, clear the signal
and follow normal RW_A/RW_B path. This allows dual-boot between stock
ChromeOS and an alternative payload while keeping compatibility with
ChromeOS updates.
