Looks like the tvOS simulator build fails due to disk space, I know @steveisok was talking about that as well (we'll need to clean more stuff after each test build).

iOS is passing which is great news :)

Related: #51491 is in progress to update the library skips and activeissue the different test suites and test facts. f61bd44 Helps with saving space on disk, but I believe there are more things to clean up

I knew there was a PR! :-) Feel free to fold this into it. Most of the tests listed here were unblocked by the AppleAppBuilder fix, few by the recent System.Security.Cryptography.Algorithms work.

I think we should fold f61bd44 into this PR and get it in, since we know it works on iOS already. We can update the other PR after that :)

Microsoft.Extensions.Configuration.EnvironmentVariables.Tests timed out on tvOSSimulator, but that test wasn't touched in this PR so is unrelated :)
