commit-graph: define common usage with a macro

Browse Source 
Share the usage message between these three variables by using a
macro. Before this new options needed to copy/paste the usage
information, see e.g. 809e0327f5 (builtin/commit-graph.c: introduce
'--max-new-filters=<n>', 2020-09-18).

See b25b727494 (builtin/multi-pack-index.c: define common usage with
a macro, 2021-03-30) for another use of this pattern (but on-list this
one came first).
