Randall Spangler 782300d093 vboot2: Add previously tried slot and result to NV storage ...

This gives recovery mode information on two boots back instead of one,
which may be handy for debugging.

It also allows determining whether a failure of the current boot
should try the other slot or go to recovery, using only information
stored in NV storage.

Added crossystem support for printing the fields, and unit tests.
