If Python is built with UBSan, test_hashlib skips tests on the _sha3
extension which currently has undefined behaviors.
This change allows to run test_hashlib to check for new UBSan regression,
but the known _sha3 undefined behavior must be fixed.
Skip tests on ASAN and/or MSAN builds:
* multiprocessing tests
* test___all__
* test_concurrent_futures
* test_decimal
* test_peg_generator
* test_tools
The ASAN job of GitHub Actions no longer excludes these tests.
Also from the _asyncio C accelerator module,
and adjust one test that the change caused to fail.

(Basically, @asvetlov proposed to return False from cancel()
when there is already a pending cancellation, and I went along,
even though it wasn't necessary for the task group implementation,
and @agronholm has come up with a counterexample that fails
because of this change. So now I'm changing it back to the old
semantics (but still bumping the counter) until we can have a
proper discussion about this.)
For threads, and for multiprocessing, it's always been the case that ``args=list`` works fine when passed to ``Process()`` or ``Thread()``, and such code is common in the wild. But, according to the docs, only a tuple can be used. This brings the docs into synch with reality.

Remove the undocumented private float.__set_format__() method,
previously known as float.__set_format__() in Python 3.7. Its
docstring said: "You probably don't want to use this function. It
exists mainly to be used in Python's test suite."
Fix a bug in urllib.request.HTTPPasswordMgr.find_user_password() and
urllib.request.HTTPPasswordMgrWithPriorAuth.is_authenticated() which
allowed to bypass authorization. For example, access to URI "example.org/foobar"
was allowed if the user was authorized for URI "example.org/foo".
The locale.getdefaultlocale() function is deprecated and will be
removed in Python 3.13. Use locale.setlocale(),
locale.getpreferredencoding(False) and locale.getlocale() functions
instead.
Fix parsing a numeric literal immediately (without spaces) followed by
"not in" keywords, like in "1not in x". Now the parser only emits
a warning, not a syntax error.
Curly brackets were never allowed in namespace URIs
according to RFC 3986, and so-called namespace-validating
XML parsers have the right to reject them a invalid URIs.
libexpat >=2.4.5 has become strcter in that regard due to
related security issues; with ET.XML instantiating a
namespace-aware parser under the hood, this test has no
future in CPython.

There are several changes:
1. We now don't explicitly check for any base / sub types, because new name check covers it
2. I've also checked that `no_type_check` do not modify foreign functions. It was the same as with `type`s
3. I've also covered `except TypeError` in `no_type_check` with a simple test case, it was not covered at all
4. I also felt like adding `lambda` test is a good idea: because `lambda` is a bit of both in class bodies: a function and an assignment

* Remove task group names (for now)
We're not sure that they are needed, and once in the code
we would never be able to get rid of them.

* Pass optional name on to task in create_task()
* Remove a bunch of unused stuff
