Pex

This release fixes a bug downloading a VCS requirement from a lock when
the ambient Python interpreter used to run Pex does not meet the
`Requires-Python` constraint of the VCS requirement.

* Fix VCS lock downloads to respect target. (2094)

This release fixes a regression introduced in Pex 2.1.120 that caused
`--no-venv-site-packages-copies` (the default when using `--venv`) to
be ignored for both zipapp PEXes (the default) and `--layout packed`
PEXes.

* Fix regression in venv symlinking. (2090)

This release fixes `--lock` resolve sub-setting for local project
requirements.

* Fix lock subsetting for local projects. (2085)

This release fixes a long-standing (> 4 years old!) concurrency bug
when building the same sdist for the 1st time and racing another Pex
process doing the same sdist build.

* Guard against racing sdist builds. (2080)

This release makes `--platform` and `--complete-platform` resolves and
locks as permissive as possible. If such a resolve or lock only has an
sdist available for a certain project, that sdist will now be used if it
builds to a wheel compatible with the specified foreign platform(s).

* Attempt "cross-builds" of sdists for foreign platforms. (2075)

This release adds support for specifying `--non-hermetic-venv-scripts`
when building a `--venv` PEX. This can be useful when integrating with
frameworks that do setup via `PYTHONPATH` manipulation.

Support for Pip 23.0.1 and setuptools 67.4.0 is added via
`--pip-version 23.0.1`.

Additionally, more work towards hardening Pex against rare concurrency
issues in its atomic directory handling is included.

* Introduce `--non-hermetic-venv-scripts`. (2068)
* Wrap inter-process locks in in-process locks. (2070)
* Add support for Pip 23.0.1. (2072)
