Add pack-refs command to the CLI

This command can be used to optimize storage of references.

For a RefDirectory database, it packs non-symbolic, loose refs into
packed-refs. By default, only the references under '$GIT_DIR/refs/tags'
are packed. The '--all' option can be used to pack all the references
under '$GIT_DIR/refs'.

For Reftable, all refs are compacted into a single table.
