add FLASH_BANK_COMMAND_HANDLER macro

The FLASH_BANK_COMMAND_HANDLER provides an extended command handler
using the __COMMAND_HANDLER macro, whereby changing that macro is
sufficient to update flash handlers with the new signature.  It also
enforces uniform style and scope when implementing this handler.
