    build: env var to enable expert config options
    
    Add an additional environment variable, defaulting to disabled,
    that enables the CONFIG_EXPERT configuration option. The purpose
    of the CONFIG_EXPERT configuration option is to make non-standard
    Kconfig options visible during the configuration process. The
    CONFIG_EXPERT option is not, itself, visible during the Kconfig
    configuration process, so typical users will never see it nor
    any of the non-standard configuration options.
