SeaBIOS: Store the .config and revision in CBFS

Add a Kconfig option to store the SeaBIOS .config and version.c files
    into CBFS if using a SeaBIOS payload.  This defaults to disabled if
    using SEABIOS_STABLE, because the coreboot version specifies everything
    needed to rebuild that.  For SeaBIOS master, the version changes, and
    for User-managed builds, both the config and version are needed.
