Define *posix_venv* and *nt_venv* sysconfig installation schemes
to be used for bootstrapping new virtual environments.
Add *venv* sysconfig installation scheme to get the appropriate one of the above.
The schemes are identical to the pre-existing
*posix_prefix* and *nt* install schemes.
The venv module now uses the *venv* scheme to create new virtual environments
instead of hardcoding the paths depending only on the platform. Downstream
Python distributors customizing the *posix_prefix* or *nt* install
scheme in a way that is not compatible with the install scheme used in
virtual environments are encouraged not to customize the *venv* schemes.
When Python itself runs in a virtual environment,
sysconfig.get_default_scheme and
sysconfig.get_preferred_scheme with `key="prefix"` returns
*venv*.
Ref:
This changes the documentation for `EnvBuilder.ensure_directories(env_dir)` to match the actual behavior of that API call.
In particular, `ensure_directories()` is not affected by the state of the `upgrade` attribute, and will not cause an error to have existing directories whether or not the `clear` attribute is set.
This documentation change I believe should be valid to all python versions back to 3.6.

* "Return true/false" is replaced with "Return ``True``/``False``"
if the function actually returns a bool.
* Fixed formatting of some True and False literals (now in monospace).
* Replaced "True/False" with "true/false" if it can be not only bool.
* Replaced some 1/0 with True/False if it corresponds the code.
* "Returns <bool>" is replaced with "Return <bool>".
Add --upgrade-deps to venv module
- This allows for pip + setuptools to be automatically upgraded to the latest version on PyPI
- Update documentation to represent this change
bpo-34556: Add --upgrade to venv module
As part of the update, the documentation was updated to normalize
around the term "virtual environment" instead of relying too heavily
on "venv" for the same meaning and leading to inconsistent usage of
either.
Thanks to Steve Piercy for the patch.
