Commit Message

Support multiplatform pexes with uv lockfiles. (#23427)

Also supports building FaaS (awslambda/gcp cloud functions).

We leverage the fact that `uv` can create foreign-platform venvs
with the `--python-platform` flag. It still needs a local python
interpreter of the appropriate version, but it downloads and installs
wheels for the foreign platform. Of course there must be foreign 
platform wheels available for all distributions. If there isn't one for
some dist, uv will build from the sdist *for the local platform*, which
may lead to a later runtime error.

Closes #23339
