kconfig: implement the `mainmenu' directive
If specified, the directive must be placed at the top of the Kconfig file.
We need to change the grammar to make the mainmenu directive set the
`rootmenu' prompt. This reflect how menu_add_prompt() works internally, ie.
set the prompt of the `current_entry', pointing originally to `rootmenu'.
