    Remove the Windows GCC driver.
    
    Summary:
    This patch drops the GCC driver and instead moves
    the only remaining path that we need to keep for
    backwards compatibility to the settings file.
    
    It also generalizes the code that expands `$TopDir`
    so it can expand it within any location in the string
    and also changes it so `$TopDir` is expanded only
    after the words call because `$TopDir` can contains
    spaces which would be horribly broken.
    
    Test Plan: ./validate
