    _project.py: Allow option conditional resolution at project toplevel.
    
    There are some early loaded essentials which do not support option
    conditionals, like the declaration of options, declaration of plugins,
    project name cannot be optional, etc.
    
    However generally speaking after the essentials have been parsed out
    the options should be resolved with this.
    
    Fixes #1683
