[K/N][tests] Don't attempt to download simulator after first failure

Sometimes, e.g. due to a bug in Xcode, downloading a simulator runtime
might fail. See e.g. 89589210 here:
https://developer.apple.com/documentation/xcode-release-notes/xcode-14-release-notes

In that case, it makes little sense to try downloading the same
simulator runtime later again.
Moreover, such attempts might lead to accumulating stale downloads in
/Library/Developer/CoreSimulator/Images/Inbox/, wasting disk space.

This commit caches the download result, so that if the first attempt
fails, then the later attempts will just rethrow the same exception.
