There are a number of miscellaneous boot images at the top level of the
kconfig menu. Move these into the 'boot options' menu.

At present the autoboot options are in cmd/Kconfig but they don't really
relate to commands. They relate to booting, so move this menu under the
boot menu.

Most of the boot options are in common/Kconfig but that file is already
extremely large. Create a new Kconfig.boot to hold the boot options.
