The `pack_compression_level` configuration is currently stored in the global variable `pack_compression_level`, which makes it shared across repository instances within a single process.
Store it instead in `repo_config_values` so the value is associated with the repository from which it was read. This preserves existing behavior while avoiding cross-repository state leakage and is another step toward eliminating repository-dependent global state.
Update all references to use repo_config_values().
