commit-graph: when incompatible with graphs, indicate why
When `gc.writeCommitGraph = true`, it is possible that the commit-graph
is _still_ not written: replace objects, grafts and shallow repositories
are incompatible with the commit-graph feature.
Under such circumstances, we need to indicate to the user why the
commit-graph was not written instead of staying silent about it.
