Ahmed Ilyas f872917d33 Refactor ExtraSpecification to support default-extras (#12964) ...

## Summary

Part of #8607. This is a pure refactor aimed at paving the way for
supporting the `default-extras` configuration in the `pyproject.toml`
file.

The `ExtraSpecification` struct has been refactored to align more
closely with the
[`DependencyGroups`](256b100a9e/crates/uv-configuration/src/dependency_groups.rs (L9))
struct.
