* NSMetadataItem initWithURL: is 10.9+ so we can't run this test on
earlier bots;
* NSRunningApplication.CurrentApplication.BundleUrl is 10.10 and it
seems wrench bots don't like it;
* Added missing helper properties for iOS
* Made NSItemDownloadingStatus a "smart enum", i.e. field aware;
* Disable default .ctor for XAMCORE_4_0, such instances are unusable;
* Added `initWithURL:` for macOS [2] as it made it easier to test the
changes since macOS it allows creating instances of `NSMetadataItem`
from an URL.

Taking a screen image does not work unless there's a window server
running, which may not always be the case on bots.
So instead just create an image manually, since these tests do
not seem to be requiring any particular type of image.
