Support more createPackageContextAsUser() users.

We created this API to make it easy to pass a given UserHandle into
all Managers obtained from a given Context, which works great for
"normal" users, but we should also support special users like ALL
and CURRENT.

Also add an AutoCloseable marker to make try-with-resources easier.
