sparse-checkout: use in-process update for disable subcommand
The 'git sparse-checkout disable' subcommand returns a user to a full working directory. The old process for doing this required updating the sparse-checkout file with the "/*" pattern and then updating the working directory with core.sparseCheckout enabled. Finally, the sparse-checkout file could be removed and the config setting disabled. However, it is valuable to keep a user's sparse-checkout file intact so they can re-enable the sparse-checkout they previously used with 'git sparse-checkout init'. This is now possible with the in-process mechanism for updating the working directory.
