Mike Bayer 7fb7365622 turn off use_insertmanyvalues for SQL Server ...

we will keep trying to find workarounds, however this
patch is the "turn it off" patch

Due to a critical bug identified in SQL Server, the SQLAlchemy
"insertmanyvalues" feature which allows fast INSERT of many rows while also
supporting RETURNING unfortunately needs to be disabled for SQL Server. SQL
Server is apparently unable to guarantee that the order of rows inserted
matches the order in which they are sent back by OUTPUT inserted when
table-valued rows are used with INSERT in conjunction with OUTPUT inserted.
We are trying to see if Microsoft is able to confirm this undocumented
behavior however there is no known workaround, other than it's not safe to
use table-valued expressions with OUTPUT inserted for now.

Fixes: #9603
