[K/N][tests] Improve logging for issues with finding Xcode simulators

This commit adds more logging to help investigate problems with
finding and downloading Xcode simulators in K/N tests.

* In case K/N test infra can’t find the matching Xcode simulator
  runtime after downloading it, show output of
    xcrun simctl list runtimes --json
  and
    xcrun simctl list devices --json

* When running `xcrun xcodebuild -downloadPlatform` or
  `-downloadAllPlatforms`, always log stdout and stderr.
