Add incremental resolution benchmark to codspeed

[konstin]

There are three scenarios for the uv resolver:

• Fresh resolution: We have a set of requirements, but no lockfile. We need to figure a resolution without any prior context. These are continuously tested by resolve_warm_airflow, resolve_warm_jupyter and resolve_warm_jupyter_universal.
• Incremental resolution: We have a lockfile that gives us preferences for versions (and help prefetching), but it's incompatible or incomplete with the requirements. This happens in a lot of cases, e.g. when pyproject.toml changed due to a version upgrade, with uv lock --upgrade-package or when using uv run --with. Our goal is to resolve versions that preserve most of the existing lockfile.
• We run uv lock and the lockfile matches: We only need to check against package.metadata.requires-dist.

While we have good coverage for the first case and the last case is fast beyond the need for optimization (<20ms even for transformers with all extras), we don't have good coverage for the middle case. We should add a scenario to codspeed, with a universal resolution where the requirements changes so that they don't match uv.lock anymore.
