[gjs: 4/5] GLib: Add MAXINT64_BIGINT, MININT64_BIGINT, MAXUINT64_BIGINT constants

    GLib: Add MAXINT64_BIGINT, MININT64_BIGINT, MAXUINT64_BIGINT constants
    
    The normal GLib.MAXINT64 constants will log a warning when used because
    their values won't fit into a JS Number. Add overrides that give these
    values as purely BigInt constants.
