rCOMM48e72dc9548c: [CommCoreModule] Remove `last[NavigatedTo/Pruned]` from `MessageStoreThread`…

Summary

IMPORTANT: While I tested this migration a few times and read through things as carefully as I could, making changes to C++ codebase and SQLite store can be risky. Adding @ashoat and @kamil as blocking to take a look... would appreciate careful review to ensure everything is correct.

In this diff we:

Remove lastPruned/lastNavigatedTo from MessageStoreThread struct and remove usages on C++ side.
Introduce SQLite migration that drops lastPruned and lastNavigatedTo columns.

As of D9475, we've started ignoring what's persisted here in SQLite entirely... so this is effectively just dead code that we're cleaning up.

Depends on

D9475

Test Plan

C++ codebase continues to build/run without issue.
recreate_message_store_threads_table migration succeeded and new message_store_threads table is as expected:

399	IMO The migrations at the top of `SQLiteQueryExecutor` are super long and take up a lot of the file. Would be good to move these to a separate `migrations` file.. or even a `migrations` folder where each migration gets its own file.
