GEODE-6641: Add ClientTransactionXATest to run

[moleske]

• sort integration tests in CMakeLists

#486 Added this test, but since it was never added to CMakeLists it didn't run in the integration tests. I sorted the CMakeLists entries in hopes that it'll be easier to see missing tests. I only ran this test on Kubuntu 20.04 since my Windows build has been failing for awhile building with VS2019 (some sort of ACE building error). Also it was missing cluster.start() so the test wasn't initially working.
