boot: Add support for VBE for the OS

When booting an OS it is useful to be able to read devicetrees provided by the OEM, from a separate FIT to the OS. Add a new method which supports this, along with the usual A/B/recovery flows, using a state file on the boot device. Signed-off-by: Simon Glass <sjg@chromium.org>
