The `core_sparse_checkout_cone` variable was previously a global integer, uninitialized by default. Storing repository-dependent configuration in globals can lead to cross-repository state leakage.
Move it into `repo_config_values` and initialize it to 0 by default. This ensures predictable behavior for repositories that do not set this configuration while preserving existing semantics.
Update all references to use repo_config_values().
