[infra][iOS] Fully build smoke tests on azdo build images

[matouskozak]

Build Mono smoke tests on Azdo build images to work around an issue where helix machines have lower XCode than Azdo images, causing Mono linking errors: #120589 (comment)

Changes:

• Correct Directory.Build.* imports for functional tests
• Tweak src/libraries/sendtohelix-mobile.targets to handle cases where only runonly tests are prepared for sending to helix.
• Rename mobile jobs running only smoke tests

I've tried building full libraries suit on macOS azdo machine but it took over 4h and then got cancelled (https://dev.azure.com/dnceng-public/public/_build/results?buildId=1220044&view=logs&jobId=6ad81d5f-e956-5767-2437-61a9fc4dc8db&j=acac6bf3-3edd-5022-4e45-3362a02520b1&t=311ccc8e-0304-52d0-3115-8f8cb0052fd2), we will need the helix build step when helix queues get updated.
