Upgrade Pex to 2.1.65. (Cherry-pick of #14256)

[jsirois]

This picks up a support for mac universal2 wheels. This support is
pressing since cryptography publishes these things and crytography is a
library folks tend to have in their transitive dependency set.

The intervening changelogs are here:

• https://github.com/pantsbuild/pex/releases/tag/v2.1.65
• https://github.com/pantsbuild/pex/releases/tag/v2.1.64
• https://github.com/pantsbuild/pex/releases/tag/v2.1.63
• https://github.com/pantsbuild/pex/releases/tag/v2.1.62

Fixes #14244

(cherry picked from commit 3f5f4d2)

The cherry-pick was not clean in lock files; so I re-generated the 2 relevant ones. The local commit hook showed this as well:

𐄂 MyPy failed.

So I had to commit -n. I did not find either 2.9.x red actions (no one cherry-picked and ignore this problem) nor did I see changes to mypy version nor the 2 erroring files on this branch; so I'm stumped and have lazily pushed this PR to see what CI thinks before thinking harder about this mystery.

[jsirois]

OK, sanity checked, same error in CI: https://github.com/pantsbuild/pants/runs/5335784833?check_suite_focus=true#step:10:328

Digging...

[jsirois]

Aha - these 2 bumps (freezegun & setuptools) trigger the unused type[ignore] warnings. I'll hand roll those fixes into those non-production files instead of altering locks.

Thank you!
