add ability to test for dialect transaction support

Transaction support is currently very limited in the MSSQL dialect,
this allows us to conditionally skip transaction related tests for
a given dialect. I imagine it's also a nice feature to have when
adding a new dialect, so you don't have to solve all one thousand
errors at the same time
