[PATCH v4 0/5] android_ab: introduce bcb ab_dump command and provide several bcb fixes

The patch series include changes:
    - move ab_select_slot() documentation to @ notation
    - move ab_select command to bcb subcommands
    - introduce the ab_dump command to print the content of the BCB
      block; it's useful for debugging A/B logic on supported boards
    - fix the slot suffix format in the ABC block to align with official
      Android BCB specifications
    - add a test for the ab_dump command to verify the accuracy of each
      field within the ABC data displayed, it's also useful for testing
      slot_suffix problem code paths

Changes v3 since v2 at [2]:
    - return "Legend" block for bcb command
    - additionally, verify the CONFIG_ANDROID_AB configuration alongside
      CONFIG_CMD_BCB to ensure that the A/B scheme is used for the
      designated board.

Changes v2 since v1 at [1]:
    - move ab_select_slot() documentation to @ notation
    - move ab_select command to bcb subcommands per Simon and Mattijs
      suggestions
    - redesign ab_dump as bcb subcommand
    - use spaces instead of tabs in the ab_dump command output
    - print hex values in the lowercase
    - add RvB tags

- resolve merge conflicts with latest master
- provide additional trailers from the previous version (excluding
  changed patches)
