Re-land [shared_preferences] Add shared preferences devtool (#8531)
Re-re-lands https://github.com/flutter/packages/pull/8494 with a change to remove --ignored from the git status check in the repo tooling publish command, which is what caused the release failure in the last landing. pub publish has ignored files in .gitignore for years, so there's no longer any value in checking that they don't exist.
I've verified that publish --dry-run passes locally with this change. Server-only check failures could still potentially cause another revert, but those can't be found other than the hard way.
