gh-108550: Speed up sqlite3 tests (GH-108551)
Refactor the CLI so we can easily invoke it and mock command-line
arguments. Adapt the CLI tests so we no longer have to launch a
separate process.
Disable the busy handler for all concurrency tests; we have full
control over the order of the SQLite C API calls, so we can safely
do this.
The sqlite3 test suite now completes ~8 times faster than before.

Modify managed_connect() helper to support in-memory databases. Use it
for the regression tests added in GH-27844.

* MemoryError is now raised instead of sqlite3.Warning when
memory is not enough for encoding a statement to UTF-8
in Connection.__call__() and Cursor.execute().
* UnicodEncodeError is now raised instead of sqlite3.Warning when
the statement contains surrogate characters
in Connection.__call__() and Cursor.execute().
* TypeError is now raised instead of ValueError for non-string
script argument in Cursor.executescript().
* ValueError is now raised for script containing the null
character instead of truncating it in Cursor.executescript().
* Correctly handle exceptions raised when getting boolean value
of the result of the progress handler.
* Add many tests covering different corner cases.

MemoryError raised in user-defined functions will now preserve
its type. OverflowError will now be converted to DataError.
Previously both were converted to OperationalError.
1. Rewrite ThreadTests with a _run_test() helper method that does the heavy lifting
2. Add test.support.threading_helper.reap_threads to _run_test()
3. Use _run_test() in all threading tests
4. Add test case for sqlite3.Connection.set_trace_callback
5. Add test case for sqlite3.Connection.create_collation
The sqlite3 module now fully implements the GC protocol, so there's no
need for this workaround anymore.
- Add and use managed resource helper for connections using TESTFN
- Sort test imports
- Split open-tests into their own test case
