For now, all Resources are implemented with a modification time, but the
public API has been left as an Optional since abstractly, not all
resources will have a modification time.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

The construct `adopt_ref(*new Obj(TRY(get_resource())))` is another
manifestation of a classic anti-pattern. In old C++, you would leak the
object's memory if the argument threw an exception, or if a member
initializer threw an exception. In our case, we leak if the MappedFile
returns an Error. This is pretty concerning, and we should avoid this
pattern at all costs, and try to use the "safer" helpers whenever
possible.
