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.
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.

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.
Adds a regression test.
Expands the documentation to clarify the behavior.

This is a first edition, ready to go out with the implementation. We'll iterate during the rest of the period leading up to 3.10.0.

The note about the GIL was buried pretty deep in the threading documentation,
and this made it hard for first time users to discover why their attempts
at using threading to parallelizing their application did not work.
In this commit, the note is moved to the top of the module documention for
visibility.
Printing to IDLE's Shell is often slower than printing to a system
terminal, but it can be made faster by pre-formatting a single
string before printing.
Unittest discovery support namespace package as start
directory. But it doesn't find namespace package in
the start directory automatically.
Otherwise, unittest discovery search into unexpected
directories like `vendor/` or `node_modules/`.
For some mysterious reason we have PySet_Check, PyFrozenSet_Check, PyAnySet_Check, PyAnySet_CheckExact and PyFrozenSet_CheckExact but no PySet_CheckExact.
The types.FunctionType constructor now inherits the current builtins
if the globals dictionary has no "__builtins__" key, rather than
using {"None": None} as builtins: same behavior as eval() and exec()
functions.
Defining a function with "def function(...): ..." in Python is not
affected, globals cannot be overriden with this syntax: it also
inherits the current builtins.
PyFrame_New(), PyEval_EvalCode(), PyEval_EvalCodeEx(),
PyFunction_New() and PyFunction_NewWithQualName() now inherits the
current builtins namespace if the globals dictionary has no
"__builtins__" key.
* Add _PyEval_GetBuiltins() function.
* _PyEval_BuiltinsFromGlobals() now uses _PyEval_GetBuiltins() if
builtins cannot be found in globals.
* Add tstate parameter to _PyEval_BuiltinsFromGlobals().
