py-anyio: updated to 3.7.0

**3.7.0**

- Dropped support for Python 3.6
- Improved type annotations:

  - Several functions and methods that were previously annotated as accepting
    ``Coroutine[Any, Any, Any]`` as the return type of the callable have been \ 
amended to
    accept ``Awaitable[Any]`` instead, to allow a slightly broader set of \ 
coroutine-like
    inputs, like ``async_generator_asend`` objects returned from the ``asend()`` \ 
method
    of async generators, and to match the ``trio`` annotations:

    - ``anyio.run()``
    - ``anyio.from_thread.run()``
    - ``TaskGroup.start_soon()``
    - ``TaskGroup.start()``
    - ``BlockingPortal.call()``
    - ``BlockingPortal.start_task_soon()``
    - ``BlockingPortal.start_task()``

    Note that this change involved only changing the type annotations; run-time
    functionality was not altered.

  - The ``TaskStatus`` class is now a generic protocol, and should be parametrized to
    indicate the type of the value passed to ``task_status.started()``
  - The ``Listener`` class is now covariant in its stream type
  - ``create_memory_object_stream()`` now allows passing only ``item_type``
  - Object receive streams are now covariant and object send streams are \ 
correspondingly
    contravariant
- Changed ``TLSAttribute.shared_ciphers`` to match the documented semantics of
  ``SSLSocket.shared_ciphers`` of always returning ``None`` for client-side streams
- Fixed ``CapacityLimiter`` on the asyncio backend to order waiting tasks in the FIFO
  order (instead of LIFO) (PR by Conor Stevenson)
- Fixed ``CancelScope.cancel()`` not working on asyncio if called before entering the
  scope
- Fixed ``open_signal_receiver()`` inconsistently yielding integers instead of
  ``signal.Signals`` instances on the ``trio`` backend
- Fixed ``to_thread.run_sync()`` hanging on asyncio if the target callable raises
  ``StopIteration``
- Fixed ``start_blocking_portal()`` raising an unwarranted
  ``RuntimeError: This portal is not running`` if a task raises an exception \ 
that causes
  the event loop to be closed
- Fixed ``current_effective_deadline()`` not returning ``-inf`` on asyncio when the
  currently active cancel scope has been cancelled (PR by Ganden Schaffner)
- Fixed the ``OP_IGNORE_UNEXPECTED_EOF`` flag in an SSL context created by default in
  ``TLSStream.wrap()`` being inadvertently set on Python 3.11.3 and 3.10.11
- Fixed ``CancelScope`` to properly handle asyncio task uncancellation on Python 3.11
  (PR by Nikolay Bryskin)
- Fixed ``OSError`` when trying to use ``create_tcp_listener()`` to bind to a \ 
link-local
  IPv6 address (and worked around related bugs in ``uvloop``)
- Worked around a `PyPy bug \ 
<https://foss.heptapod.net/pypy/pypy/-/issues/3938>`_
  when using ``anyio.getaddrinfo()`` with for IPv6 link-local addresses containing
  interface names
