Added an invalidate_caches() method to the zipimport.zipimporter class based on the implementation of importlib.FileFinder.invalidate_caches(). This was done by adding a get_files() method and an _archive_mtime attribute to zipimport.zipimporter to check for updates or cache invalidation whenever the cache of files and toc entry information in the zipimporter is accessed.

We now buffer the CONNECT request + tunnel HTTP headers into a single
send call.  This prevents the OS from generating multiple network
packets for connection setup when not necessary, improving efficiency.

In the [official tutorial on virtual environment](https://docs.python.org/3/tutorial/venv.html#creating-virtual-environments)

> This will create the tutorial-env directory if it doesn’t exist, and also create directories inside it containing a copy of the Python interpreter, **the standard library**, and various supporting files.

According to the actual behavior of `venv` and [PEP 405](https://www.python.org/dev/peps/pep-0405/#id15)'s description about virtual environment, no standard library file is included in the virtual environment's directory.

DeprecationWarnings were being raised in the test_encode_decimal()
and test_transform_decimal() methods after 91a639a.

This approach ensures the code matches the interpreter version.
Previously, PYTHON_FOR_REGEN was used to generate the code, which might
be wrong. The marshal format for code objects has changed with
bpo-42246, commit 877df85. Update the code and the expected code sizes
in ctypes test_frozentable.

Previous wording implied that only the result of call N and N+1 could be

…ries to execute a non-Python signal handler (GH-24756)

We can receive signals (at the C level, in `trip_signal()` in signalmodule.c) while `signal.signal` is being called to modify the corresponding handler.  Later when `PyErr_CheckSignals()` is called to handle the given signal, the handler may be a non-callable object and would raise a cryptic asynchronous exception.

This is friendlier to other in-process code that an extension module or
embedding use could pull in such as CGo where tiny stacks are the norm
and sigaltstack() has been used to provide for signal handlers.

Without this, signals received by a process using tiny stacks may lead
to stack overflow crashes.

* Apply changes from importlib_resources 5.0.4

#24753)

This reverts commit cb7bc76.

The following changes are required:

      * add a new platform win-arm64
      * replace the emulated compiler executable paths
      * bump the linker base addressed as ARM64 requires more memory
        this change might not be needed (investigation required)

    On Windows 10 ARM64, VS compiler paths look like this:
    C:\Program Files (x86)\Microsoft Visual
    Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\HostX86\ARM64\cl.exe

    Note that the cl.exe for ARM64 is an x32 binary, which can run emulated
    on Windows 10 ARM64 (it has builtin emulation for x32).

    The rc.exe and mc.exe paths have to also be changed, as the initial
    discovery has to be fixed.

    Work in progress to remove the hardcoded bits and to change the path
    query fixes to the proper location.

The case of tempfile.tempdir variable being bytes is now handled consistently.
The getters return the right type and no more error of mixing str and bytes unless explicitly caused by the user.

Previously, `datetime.strptime` would match `'z'` with the format string `'%z'` (for UTC offsets), throwing an `IndexError` by erroneously trying to parse `'z'` as a timestamp. As a special case, `'%z'` matches the string `'Z'` which is equivalent to the offset `'+00:00'`, however this behavior is not defined for lowercase `'z'`.

This change ensures a `ValueError` is thrown when encountering the original example, as follows:

```
>>> from datetime import datetime
>>> datetime.strptime('z', '%z')
ValueError: time data 'z' does not match format '%z'
```
