Handle Windows AV/EDR file locks during script installations (#9543)
Fixes #9531


## Context

While working with [uv](https://github.com/astral-sh/uv), I encountered
issues with a python dependency, [httpx](https://www.python-httpx.org/)
unable to be installed because of a **os error 5 permission denied**.
The error occur when we try to persist a **.exe file** from a temporary
folder into a persistent one.
I only reproduce the issue in an enterprise **Windows** Jenkins Runner.
In my virtual machines, I don't have any issues. So I think this is most
probably coming from the system configuration. This windows runner
**contains an AV/EDR**. And the fact that the file locked occured only
once for an executable make me think that it's most probably the cause.

While doing some research and speaking with some colleagues (hi
@vmeurisse), it seems that the issue is a very recurrent one on Windows.
In the Javascript ecosystem, there is this package, created by the
@isaacs, `npm` inventor: https://www.npmjs.com/package/graceful-fs, used
inside `npm`, allowing its package installations to be more resilient to
filesystem errors:
> The improvements are meant to normalize behavior across different
platforms and environments, and to make filesystem access more resilient
to errors.
One of its core feature is this one:
> On Windows, it retries renaming a file for up to one second if EACCESS
or EPERM error occurs, likely because antivirus software has locked the
directory.

So I tried to implement the same algorithm on `uv`, **and it fixed my
issue**! I can finally install `httpx`.

Then, [as I mentionned in this
issue](https://github.com/astral-sh/uv/issues/9531#issuecomment-2508981316),
I saw that you already implemented exactly the same algorithm in an
asynchronous function for renames 😄

## Summary of changes 
- I added a similar function for `persist` (was not easy to have the
benediction of the borrow checker 😄)
- I added a `sync` variant of `rename_with_retry`
- I edited `install_script` to use the function including retries on
Windows

Let me know if I should change anything 🙂 

Thanks!!

## Test Plan
This pull-request should be totally iso-functional, so I think it should
be covered by existing tests in case of regression.
All tests are still passing on my side.
Also, of course validated that my windows machines (windows 10 & windows
11) containing AV/EDR software are now able to install `httpx.exe`
script.
However, if you think any additional test is needed, feel free to tell
me!
