Added Azure DevOps Pipeline (#776)

* Trying to get an older linux build * Switch to clang 3.8 on linux. #686 * Statically link things for linux * Set up CI with Azure Pipelines * Updated the tizen install script to work on macos and linux * Make sure to install the version of the Android NDK we support * Added missing [SkippableFact] attribute
