[issue44092] [sqlite3] Remove special rollback handling

I think this change is no problem.
Erlend E. Aasland's explanation is very clear. 

There is only one situation that a problem may occur. Write code with SQLite 3.8.7.2+ (2014-11-18), and run it on 3.7.15 (2012-12-12) ~ 3.8.7.1-, but this situation may be difficult to happen, we can note this situation in doc.

More securely, if run on SQLite 3.8.7.1-, and encounter SQLITE_ABORT_ROLLBACK error code, a prompt can be given to explain the reason.

Also note that the current main branch is buggy. If don't adopt this change or revert this change later, don't forget to fix the bug of msg407185 (`pysqlite_Statement.in_use` flag is not reset).
