commit-graph: collapse parameters into flags

The write_commit_graph() and write_commit_graph_reachable() methods
currently take two boolean parameters: 'append' and 'report_progress'.
As we update these methods, adding more parameters this way becomes
cluttered and hard to maintain.

Collapse these parameters into a 'flags' parameter, and adjust the
callers to provide flags as necessary.
