Move architecture and operating system probing to Python (#2381) 
The architecture of uv does not necessarily match that of the python
interpreter (#2326). In cross compiling/testing scenarios the operating
system can also mismatch. To solve this, we move arch and os detection
to python, vendoring the relevant pypa/packaging code, preventing
mismatches between what the python interpreter was compiled for and what
uv was compiled for.

To make the scripts more manageable, they are now a directory in a
tempdir and we run them with `python -m` . I've simplified the
pypa/packaging code since we're still building the tags in rust. A
`Platform` is now instantiated by querying the python interpreter for
its platform. The pypa/packaging files are copied verbatim for easier
updates except a `lru_cache()` python 3.7 backport.

Error handling is done by a `"result": "success|error"` field that allow
passing error details to rust:

```console
$ uv venv --no-cache
  × Can't use Python at `/home/konsti/projects/uv/.venv/bin/python3`
  ╰─▶ Unknown operation system `linux`
```

I've used the [maturin sysconfig
collection](855f6d2cb1/sysconfig)
as reference. I'm unsure how to test these changes across the wide
variety of platforms.

Readme.md

Reimplementation of wheel installing in rust. Supports both classical venvs and monotrail.

There are simple python bindings:

from install_wheel_rs import LockedVenv

locked_venv = LockedVenv("path/to/.venv")
locked_venv.install_wheel("path/to/some_tagged_wheel.whl")

and there's only one function: install_wheels_venv(wheels: List[str], venv: str), where wheels is a list of paths to wheel files and venv is the location of the venv to install the packages in.

See monotrail for benchmarks.
