feat(flags): improve help output and make `deno run` list tasks (#25108)

- rewrite flag help
- use gray for indentation
- reorganize permission flags and split them up
- make help subcommand act like help flag
- `deno run` outputs list of tasks
- Fixes #25120

error handling for `deno run` in case of no config file being found
needs to be improved
