If a user wishes to use the multi-pack-index feature, then they must enable this config and run 'git multi-pack-index write'. The multi-pack-index feature is relatively stable now, so make the config option true by default. For users that do not use a multi-pack-index, the only extra cost will be a file lookup to see if a multi-pack-index file exists (once per process, per object directory). Also, this config option will be referenced by an upcoming "incremental-repack" task in the maintenance builtin, so move the config option into the repository settings struct. Note that if GIT_TEST_MULTI_PACK_INDEX=1, then we want to ignore the config option and treat core.multiPackIndex as enabled.
