feat(vcs): implement VcsDriverInterface for all VCS drivers

Reconcile the VcsDriverInterface trait with the concrete drivers so every
driver implements it as in PHP, where each driver extends VcsDriver.

- Make cache-mutating getters take &mut self in the trait, matching the
  inherent methods' lazy-cache semantics; update vcs_repository consumers.
- Change supports() to take Rc<RefCell<Config>> and return Result<bool>,
  completing GitDriver::supports deep ls-remote and its config wiring.
- Add base get_composer_information to Git/Hg/Fossil/Perforce and an
  impl VcsDriverInterface block to every driver, delegating to inherent
  methods and absorbing type differences in the impl.
