rebase: stop reading and writing unnecessary strategy state

The state files for "--strategy" and "--strategy-option" are written and read twice, once by builtin/rebase.c and then by sequencer.c. This is an artifact of the scripted rebase and the need to support "rebase --preserve-merges". Now that "--preserve-merges" no-longer exists we only need to read and write these files in sequencer.c. This enables us to remove a call to free() in read_strategy_opts() that was added by f1f4ebf432 (sequencer.c: fix "opts->strategy" leak in read_strategy_opts(), 2022-11-08) as this commit fixes the root cause of that leak. There is further scope for removing duplication in the reading and writing of state files between builtin/rebase.c and sequencer.c but that is left for a follow up series.
