[chore] Use bulk updates + fewer loops in status rethreading migration (#4459)
This pull request tries to optimize our status rethreading migration by using bulk updates + avoiding unnecessary writes, and doing the migration in one top-level loop and one stragglers loop, without the extra loop to copy thread_id over. On my machine it runs at about 2400 rows per second on Postgres, now, and about 9000 rows per second on SQLite. Tried *many* different ways of doing this, with and without temporary indexes, with different batch and transaction sizes, etc., and this seems to be just about the most performant way of getting stuff done. With the changes, a few minutes have been shaved off migration time testing on my development machine. *Hopefully* this will translate to more time shaved off when running on a vps with slower read/write speed and less processor power. SQLite before: ``` real 20m58,446s user 16m26,635s sys 5m53,648s ``` SQLite after: ``` real 14m25,435s user 12m47,449s sys 2m27,898s ``` Postgres before: ``` real 28m25,307s user 3m40,005s sys 4m45,018s ``` Postgres after: ``` real 22m31,999s user 3m46,674s sys 4m39,592s ``` Reviewed-on: https://codeberg.org/superseriousbusiness/gotosocial/pulls/4459 Co-authored-by: tobi <tobi.smethurst@protonmail.com> Co-committed-by: tobi <tobi.smethurst@protonmail.com>
