builtin rebase: support `--autosquash`

This commit adds support for the `--autosquash` option which is used to automatically squash the commits marked as `squash` or `fixup` in their messages. This is converted following `git-legacy-rebase.sh` closely. This option can also be configured via the Git config setting rebase.autosquash. To support this, we also add a custom rebase_config() function in this commit that will be used instead (and falls back to) git_default_config().
