  2. feat: allow DDL with autocommit=false (#3057)
    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

Uses the gson Java version checker, which is more production-hardened than the custom one in the Spanner client. It seems that the Spanner implementation does not get it right on all versions on Windows.
