parselist: move the function from config to stringutil

We move the function in a lower level module to avoid cycle. It moves next to
`parsebool` who had to migrate for the same reasons.

    /// Returns the corresponding list-value in the config if found, or `None`.
    ///
    /// This is appropriate for new configuration keys. The value syntax is
    /// **not** the same as most existing list-valued config, which has Python
    /// parsing implemented in `parselist()` in `mercurial/config.py`.
    /// Faithfully porting that parsing algorithm to Rust (including behavior
    /// that are arguably bugs) turned out to be non-trivial and hasn’t been
    /// completed as of this writing.
    ///
    /// Instead, the "simple" syntax is: split on comma, then trim leading and
    /// trailing whitespace of each component. Quotes or backslashes are not
    /// interpreted in any way. Commas are mandatory between values. Values
    /// that contain a comma are not supported.
