Stable order for virtual packages (#10024)

uv gives priorities to packages by package name, not by virtual package
(`PubGrubPackage`). pubgrub otoh when prioritizing order the virtual
packages. When the order of virtual packages changes, uv changes its
resolutions and error messages. This means uv was depending on
implementation details of pubgrub's prioritization caching.

This broke with https://github.com/pubgrub-rs/pubgrub/pull/299, which
added a tiebreaker term that made pubgrub's sorting deterministic given
a deterministic ordering of allocating the packages (which happens the
first time pubgrub sees a package).

The new custom tiebreaker decreases the difference to upstream pubgrub.
