Subject: [PATCH] system/nxinit: Add boot support for action

Add support for booting a new application firmware image.
Depends on `BOARDCTL_BOOT_IMAGE`.

When the built-in boot command of nsh is enabled, the built-in boot
command of Init will take precedence (see init_builtin_run()). To use
the built-in boot command of nsh, use: `exec -- sh boot [args...]`.

Referred to nshlib/nsh_syscmds.c: cmd_boot()
