Add a `debug_mode: bool` fixture via `--tpdb` flag
Allows tests (including any `@tractor_test`s) to subscribe to a CLI flag `--tpdb` (for "tractor python debugger") which the session can provide to tests which can then proxy the value to `open_root_actor()` (via `open_nursery()`) when booting the runtime - thus enabling our debug mode globally to any subscribers B) This is real handy if you have some failures but can't determine the root issue without jumping into a `pdbp` REPL inside a (sub-)actor's spawned-task.modden_spawn_from_client_req
