Tyler Goodlet 9221c57234 Adjust all `RemoteActorError.type` using tests
To instead use the new `.boxed_type` B)

Tyler Goodlet 71de56b09a Drop now-deprecated deps on modern `trio`/Python
- `trio_typing` is nearly obsolete since `trio >= 0.23`
- `exceptiongroup` is built-in to python 3.11
- `async_generator` primitives have lived in `contextlib` for quite
  a while!

Tyler Goodlet 96992bcbb9 Add (back) a `tractor._testing` sub-pkg
Since importing from our top level `conftest.py` is not scaleable
or as "future forward thinking" in terms of:
- LoC-wise (it's only one file),
- prevents "external" (aka non-test) example scripts from importing
  content easily,
- seemingly(?) can't be used via abs-import if using
  a `[tool.pytest.ini_options]` in a `pyproject.toml` vs.
  a `pytest.ini`, see:
  https://docs.pytest.org/en/8.0.x/reference/customize.html#pyproject-toml)

=> Go back to having an internal "testing" pkg like `trio` (kinda) does.

Deats:
- move generic top level helpers into pkg-mod including the new
  `expect_ctxc()` (which i needed in the advanced faults testing script.
- move `@tractor_test` into `._testing.pytest` sub-mod.
- adjust all the helper imports to be a `from tractor._testing import <..>`

Rework `test_ipc_channel_break_during_stream()` and backing script:
- make test(s) pull `debug_mode` from new fixture (which is now
  controlled manually from `--tpdb` flag) and drop the previous
  parametrized input.
- update logic in ^ test for "which-side-fails" cases to better match
  recently updated/stricter cancel/failure semantics in terms of
  `ClosedResouruceError` vs. `EndOfChannel` expectations.
- handle `ExceptionGroup`s with expected embedded errors in test.
- better pendantics around whether to expect a user simulated KBI.
- for `examples/advanced_faults/ipc_failure_during_stream.py` script:
  - generalize ipc breakage in new `break_ipc()` with support for diff
    internal `trio` methods and a #TODO for future disti frameworks
  - only make one sub-actor task break and the other just stream.
  - use new `._testing.expect_ctxc()` around ctx block.
  - add a bit of exception handling with `print()`s around ctxc (unused
    except if 'msg' break method is set) and eoc cases.
  - don't break parent side ipc in loop any more then once
    after first break, checked via flag var.
  - add a `pre_close: bool` flag to control whether
    `MsgStreama.aclose()` is called *before* any ipc breakage method.

Still TODO:
- drop `pytest.ini` and add the alt section to `pyproject.py`.
 -> currently can't get `--rootdir=` opt to work.. not showing in
   console header.
 -> ^ also breaks on 'tests' `enable_modules` imports in subactors
   during discovery tests?

Tyler Goodlet 8c39b8b124 Tweak some tests for spurious failues
With the seeming cause that some cases occasionally raise
`ExceptionGroup` instead of a (collapsed out) single error which, in
those cases at least try to check that `.exceptions` has the original
error.

Tyler Goodlet 38d03858d7 Fix `asyncio`-task-sync and error propagation
This fixes an previously undetected bug where if an
`.open_channel_from()` spawned task errored the error would not be
propagated to the `trio` side and instead would fail silently with
a console log error. What was most odd is that it only seems easy to
trigger when you put a slight task sleep before the error is raised
(:eyeroll:). This patch adds a few things to address this and just in
general improve iter-task lifetime syncing:

- add `LinkedTaskChannel._trio_exited: bool` a flag set from the `trio`
  side when the channel block exits.
- add a `wait_on_aio_task: bool` flag to `translate_aio_errors` which
  toggles whether to wait the `asyncio` task termination event on exit.
- cancel the `asyncio` task if the trio side has ended, when
  `._trio_exited == True`.
- always close the `trio` mem channel when the task exits such that
  the `asyncio` side can error on any next `.send()` call.

Tyler Goodlet 04c0eda69d Add an `asyncio`-internal cancel test
Verify that if the `asyncio` side task cancels (itself) that we raise
that `asyncio.CancelledError` on the `trio` side.  In the case where
`trio` initiated the cancel whether or not the `asyncio` side ended up
raising `CancelledError` doesn't really matter to us as long as the far
task did indeed terminate.
