Fix 'No transaction found' error on Synapse.
Fixed issue where the SQL Server dialect's query for the current isolation
level would fail on Azure Synapse Analytics, due to the way in which this
database handles transaction rollbacks after an error has occurred. The
initial query has been modified to no longer rely upon catching an error
when attempting to detect the appropriate system view. Additionally, to
better support this database's very specific "rollback" behavior,
implemented new parameter ``ignore_no_transaction_on_rollback`` indicating
that a rollback should ignore Azure Synapse error 'No corresponding
transaction found. (111214)', which is raised if no transaction is present
in conflict with the Python DBAPI.
