treewide: bcb: move ab_select command to bcb subcommands

Browse Source 
To enhance code organization, it is beneficial to consolidate all A/B
BCB management routines into a single super-command.
The 'bcb' command is an excellent candidate for this purpose.

This patch integrates the separate 'ab_select' command into the 'bcb'
group as the 'ab_select' subcommand, maintaining the same parameter list
for consistency.
