mb/lenovo/*: Add support for VBOOT on 8MiB devices
Enable VBOOT support on all devices that have a 8 MiB flash, using a
single RW_MAIN_A partition, allowing the use of tianocore payload in
both RW_MAIN_A and WP_RO.
* Add VBNV section to cmos.layout
* Add FMAP for VBOOT and regular boot
* Select Kconfigs for VBOOT
* Enable VBOOT_SLOTS_RW_A by default
Also build test VBOOT on Lenovo T420.
Tested on Lenovo T520 using Icb7b263ed86551cc53e1db7babccaca6b3ae2fe6.
