tint: Strip aliases that reference unused overrides

The SingleEntryPoint transform currently does not strip away any
unused type declarations, which was leading to broken code when an
alias referenced an override that was removed. We can detect this
scenario and remove such aliases, until we have a better mechanism for
detecting all unused aliases.

Fixed: tint:1763
