[RFC PATCH 1/2] commit-graph.c: add "flags" to lookup_commit_in_graph()

In-Reply-To
<cover.1655350442.git.hanxin.hx@bytedance.com>

When try to do deref_without_lazy_fetch_extended(), "oi_flags" will be missed by lookup_commit_in_graph(), then repo_has_object_file() may start a new round objects fetching. So let's add "flags" to lookup_commit_in_graph() and use repo_has_object_file_with_flags() to pass the flags.
