Global offline flag (#2335)
This PR introduces a global `--offline` flag.

## Doctor

This replaces the `--offline` flag on the doctor command.

## Juvix package builds

The flag applies to juvix build commands like `juvix compile`, `juvix
repl`. This is so that users can continue to build packages offline that
have external dependencies when there's no network connection (as long
as they built the same package online previously).

Specifically, when the `--offline` flag is used in a package that has
external git dependencies.
* No `git clone` or `git fetch` commands are used
* `git checkout` will continue to be used
* Clones from previous builds are reused

This means that you can update the `ref` field in a git dependency, as
long as the ref existed the last time that the project was built without
the `--offline` flag.

* Closes https://github.com/anoma/juvix/issues/2333
