fix: op_set_exit_code (#13034) Fixes "op_set_exit_code" by sharing a single "Arc" between all workers (via "op state") instead of having a "global" value stored in "deno_runtime" crate. As a consequence setting an exit code is always scoped to a tree of workers, instead of being overridable if there are multiple worker tree (like in "deno test --jobs" subcommand). Refactored "cli/main.rs" functions to return "Result<i32, AnyError>" instead of "Result<(), AnyError>" so they can return exit code. 2021-12-11 09:56:45 -05:00			`// Set exit code`
