Implement Oracle SERIALIZABLE + real read of isolation level
There's some significant awkwardness in that we can't
read the level unless a transaction is started, which normally
does not occur unless DML is emitted. The implementation
uses the local_transaction_id function to start a transaction.
It is not known what the performance impact of this might
have, however by default the function is called only once
on first connect and later only if the get_isolation_level()
method is used.
Fixes: #5755
