refactor(repository): make read methods fallible and take &mut self

Change RepositoryInterface and WritableRepositoryInterface read methods
(find_package, find_packages, get_packages, load_packages, search,
get_providers, get_canonical_packages) to take &mut self and return
anyhow::Result, so lazy-loading repositories such as ComposerRepository
can perform fallible I/O and mutate internal state on access. Update all
implementors and call sites to propagate the Result and pass mutable
references.
