Add uv sync --script (#11361)

Browse source 
## Summary

The environment is located at a stable path within the cache, based on
the script's absolute path.

If a lockfile exists for the script, then we use our standard lockfile
semantics (i.e., update the lockfile if necessary, etc.); if not, we
just do a `uv pip sync` (roughly).

Example usage:

```
❯ uv init --script hello.py
Initialized script at `hello.py`

❯ uv add --script hello.py requests
Updated `hello.py`

❯ cargo run sync --script hello.py
Using script environment at: /Users/crmarsh/.cache/uv/environments-v1/hello-84e289fe3f6241a0
