Adds support for running DDL statements when a connection is in autocommit=false mode. By default, DDL statements are only allowed when no transaction is active. That is; no query or DML statement has been executed which activated a read/write transaction.

A new flag is added that can be used to revert the behavior back to the original behavior where DDL is always refused when autocommit=false. The same flag can also be used to make the API behave the same as MySQL and Oracle, where any active transaction is automatically committed whenever a DDL statement is encountered.

Concretely this means that the following is now allowed:

```
set autocommit=false;
create table Singers (SingerId INT64, Name STRING(MAX)) PRIMARY KEY (SingerId);
```

The following is by default NOT allowed, unless
ddlInTransactionMode=AUTO_COMMIT_TRANSACTION

```
set autocommit=false;
select * from singers; -- This starts a transaction
create table Albums (AlbumId INT64) PRIMARY KEY (AlbumId); -- This is not allowed
```

Adds support for overlapping transactions on the emulator in the Connection API, even when these are executed on one thread. This is normally not supported, as it requires multiple transactions to run concurrently on the emulator.

This change works around that by keeping track of what the active transaction on the emulator is, and then abort that transaction when another transaction needs to make progress. The transaction that was aborted will be retried up to the point where it was when it again wants to make progress.

This step-by-step progress is implemented by automatically setting a savepoint in the transaction after each successful step. The transaction is then rolled back to that savepoint when another transaction needs to make progress.

The feature is only enabled if the autoConfigEmulator flag is enabled.
