This PR contains:
1) Fixes of localization
2) Update for ADO CI to add Xcode 11.7 and 12 beta and remove older version in test matrix
3) Skip tests for i386 simulators, because Xcode 12 beta is not supports 10.3.1 simulator runtime (it might be fixed in next beta versions. If so, we should revert this fix)
