This PR makes `TursoDB` and `TursoDBFactory` thread-safe. I also used
the opportunity to do some minor improvements.

I modified the `better-sqlite3.spec.mjs` test suite to use the dual test
runner from https://github.com/tursodatabase/turso/pull/1941 and I
deleted the `limbo.spec.mjs` test suite, because it's now redundant.
I looked carefully at the diff between the two test suites to make sure
that we didn't lose any coverage with this change.

In reponse to [discord discussion](https://discord.com/channels/12586588
26257961020/1385754749634084885/1390535068401012858), I thought it would
be better to add a test to show how JDBC4Statement can be used.

Makes it easier to test the feature:
```
$ cargo run -- --experimental-indexes
Limbo v0.0.22
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database
limbo> CREATE TABLE t(x);
limbo> CREATE INDEX t_idx ON t(x);
limbo> DROP INDEX t_idx;
```
- `Update` query doesn't update `n_changes`. Let's make it work
- Add `InsertFlags` to add meta information related to insert operations
- For update query, add `UPDATE` flag
- Currently, the update query executes `Insn::Delete` and `Insn::Insert`
internally, it increases `n_change` by 2. So, for the update query,
let's skip increasing `n_change` for the `Insn::Insert`
