When this is merged into an actual firmware build, can test it:
* dev switch off -> no dev screen, won't boot self-signed kernel
* dev switch on --> dev warning screen, will boot self-signed kernel
(e.g., it acts like the Cr-48)

Pressing Tab at a firmware screen now displays real data, including
the recovery reason, HWID, and contents of VbNvStorage.
Entry point start/end time tracking in VbSharedData now refers to the
new wrapper APIs.
Added capability for calling firmware to request recovery mode (for
example, if it's unable to initialize RAM, can't find the SSD, etc.).
Previously, calling firmware had no (good) way to do this other than
faking the recovery button being pressed.
