MA-17338-1 Enable boot control v1.1

The old boot control logic and misc data struct is based on the
'external/avb/libavb_ab' library which is already marked as
deprecated and won't be maintained by google anymore:

    Deprecate libavb_ab and bootctrl.avb code.

    This code was already marked as experimental in anticipation of being
    removed in the future. Officially deprecate it and set Jun 1 2018 as
    the date it will be removed. This should give users of the code ample
    time to fork/migrate.

    To keep using the code AVB_AB_I_UNDERSTAND_LIBAVB_AB_IS_DEPRECATED
    must be defined.

    The reason for deprecating this code is twofold:

     - Its policy was optimized for devices without a display with
       e.g. automatic fallback to the other slot if a slot fails to
       boot. Since most A/B stacks in Android devices don't work this
       way this code is confusing.

     - There are no known active users, no good test coverage for the
       bootctrl.avb code, and no plans to use it.

    When the code is removed we'll provide an easy transition path by
    keeping (but renaming) the |ab_ops| member in AvbOps.

Google has provided a new boot control v1.1 implementation under
'hardware/interfaces/boot/1.1/default' which uses a new misc data struct defined
in the 'include/android_bootloader_message.h'. This commit adds a new boot control
implementation in bootloader, which combines the new misc data struct and inherit
some flow in 'libavb_ab', the old 'libavb_ab' library will be removed.

Test: boot/slot switch/retry count test on single&dual bootloader.
