Patrick Steinhardt 6dcffc68f4 builtin/pack-refs: introduce new "--auto" flag ...

Calling git-pack-refs(1) will unconditionally cause it to pack all
requested refs regardless of the current state of the ref database. For
example:

  - With the "files" backend we will end up rewriting the complete
    "packed-refs" file even if only a single ref would require
    compaction.

  - With the "reftable" backend we will end up always compacting all
    tables into a single table.

This behaviour can be completely unnecessary depending on the backend
and is thus wasteful.

With the introduction of the `PACK_REFS_AUTO` flag in the preceding
commit we can improve this and let the backends decide for themselves
whether to pack refs in the first place. Expose this functionality via a
new "--auto" flag in git-pack-refs(1), which mirrors the same flag in
both git-gc(1) and git-maintenance(1).
