Allow `truncate` for SQLite3 adapter and add `rails db:seed:replant` (#34779)
* Add `ActiveRecord::Base.connection.truncate` for SQLite3 adapter.
SQLite doesn't support `TRUNCATE TABLE`, but SQLite3 adapter can support
`ActiveRecord::Base.connection.truncate` by using `DELETE FROM`.
`DELETE` without `WHERE` uses "The Truncate Optimization",
see https://www.sqlite.org/lang_delete.html.
* Add `rails db:seed:replant` that truncates database tables and loads the seeds
Closes #34765
