deprecated FF140

In FF128 these were used to migrate to
- clearOnShutdown to clearOnShutdown_v2
- cpd to clearHistory

They are then no longer used.

The migration can be checked with
- privacy.sanitize.clearOnShutdown.hasMigratedToNewPrefs2
- privacy.sanitize.cpd.hasMigratedToNewPrefs2

Note: in FF136 there was another migration, where it changes the `ToNewPrefs2` to false
- privacy.sanitize.clearOnShutdown.hasMigratedToNewPrefs3
- privacy.sanitize.cpd.hasMigratedToNewPrefs3

AFAICT, cpd.hasMigrated* doesn't migrate until you open the clear history dialog.
