Pants

I have python scripts that run `pants` commands, ideally I’d like to run these via `pants run` like the rest of my targets. This requires setting `PANTS_CONCURRENT=True` to function, but a workaround is to build and run separately e.g.
```pants package &lt;pex_target&gt;
python3 dist/pex_target.pex```
Can I reach anything equivalent whilst still running via `pants run`? The execution_mode options for `pex_binary` don’t enable this, but maybe something else does.

Maybe this PR would be helpful? <https://github.com/pantsbuild/pants/pull/22418>

It's a proof of concept; I don't like the API but it does let `run` release the concurrency lock.

I like the idea of the `--loop` option allowing for explicitly telling the Pants runtime to detach itself mentioned in <https://github.com/pantsbuild/pants/issues/20642>.
