builtin/refs: add optimize subcommand 

As part of the ongoing effort to consolidate reference handling,
introduce a new `optimize` subcommand. This command provides the same
functionality and exit-code behavior as `git pack-refs`, serving as its
modern replacement.

Implement `cmd_refs_optimize` by having it call the `pack_refs_core()`
helper function. This helper was factored out of the original
`cmd_pack_refs` in a preceding commit, allowing both commands to share
the same core logic as independent peers.

Add documentation for the new command. The man page leverages the shared
options file, created in a previous commit, by using the AsciiDoc
`include::` macro to ensure consistency with git-pack-refs(1).
