feat(fwu): add a function to obtain an alternate FWU bank to boot
Add a function fwu_get_alternate_boot_bank() to return a valid bank to
boot from. This function can be called by a platform to get an
alternate bank to try to boot the platform in the unlikely scenario of
the active bank being in an invalid state, or if the number of times
the platform boots in trial state exceeds a pre-set count.

feat(fwu): modify the check for getting the FWU bank's state
The version 2 of the FWU metadata structure has a field bank_state in
the top level of the structure which can be used to check if a given
bank is in the either of Trial State, Accepted State, or in an Invalid
State. This is different from the binary states of Valid/Accepted
States that the bank could be in, as defined in the earlier version of
the specification.
Replace the fwu_is_trial_run_state() API with
fwu_get_active_bank_state() to get the state the current active bank
is in. The value returned by this API is then used by the caller to
take appropriate action.
