[run] Add --all-projects flag (jetify-com#2543)

## Summary

Allows running a script on all devbox projects nested in a directory.
Useful for monorepos. Example:

`devbox run --all-projects lint`

Doing 

`devbox run --all-projects` without a script name shows all available
scripts among all nested projects.

@savil I kinda regret changing `run` to remove the need for `--`. It
means that this flag only works for defined scripts, not for arbitrary
commands :(

## How was it tested?

`devbox run --all-projects fmt`
