    Convert a Name metadata value to a .egg-link name, by applying
    the same substitution as pkg_resources's safe_name function.
    Note: we cannot use canonicalize_name because it has a different logic.

    We also look for the raw name (without normalization) as setuptools 69 changed
    the way it names .egg-link files (https://github.com/pypa/setuptools/issues/4167).

    Look for a .egg-link file for project name, by walking sys.path.

    Return the path for the .egg-link file if it exists, otherwise, None.

    There's 3 scenarios:
    1) not in a virtualenv
       try to find in site.USER_SITE, then site_packages
    2) in a no-global virtualenv
       try to find in site_packages
    3) in a yes-global virtualenv
       try to find in site_packages, then site.USER_SITE
       (don't look in global location)

    For #1 and #3, there could be odd cases, where there's an egg-link in 2
    locations.

    This method will just return the first one found.
