This finishes the removal of ConstString from FileSpec's interface. Note that FileSpec is still _backed_ by ConstStrings, that will be changed in a follow-up. A non-goal for this change is to rewrite business logic, so I kept the type of some variables as ConstString where a refactor would necessary to change that. I converted printf-style formatting to formatv-style formatting where required, and otherwise tried to leave callsites alone to the extent that was possible.
