FTP: split the directory listing parser test and re-enable it on TSan bots

The test was disabled on TSan bots becuase it was taking too much time.
This change converts one huge test which parses ~30 directory listings
to ~30 separate test cases.

This change also moves ToLower/ToUpper from ui/base/l10n_util
to base/i18n/case_conversion so that they can be used in net/ftp.
