gh-82012: Deprecate bitwise inversion (~) of bool (#103487)
The bitwise inversion operator on bool returns the bitwise inversion of the
underlying int value; i.e. `~True == -2` such that `bool(~True) == True`.

It's a common pitfall that users mistake `~` as negation operator and actually
want `not`. Supporting `~` is an artifact of bool inheriting from int. Since there
is no real use-case for the current behavior, let's deprecate `~` on bool and
later raise an error. This removes a potential source errors for users.

Full reasoning: https://github.com/python/cpython/issues/82012#issuecomment-1258705971

gh-103793: Defer formatting task name (#103767)
The default task name is "Task-<counter>" (if no name is passed in during Task creation).
This is initialized in `Task.__init__` (C impl) using string formatting, which can be quite slow.
Actually using the task name in real world code is not very common, so this is wasted init.

Let's defer this string formatting to the first time the name is read (in `get_name` impl),
so we don't need to pay the string formatting cost if the task name is never read.

We don't change the order in which tasks are assigned numbers (if they are) --
the number is set on task creation, as a PyLong instead of a formatted string.

gh-84436: Implement Immortal Objects (gh-19474)
This is the implementation of PEP683

Motivation:

The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime.

Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.
