Core: Make isAttached work with iOS 10.0-10.2
The test for Shadow DOM v1 support has been changed to rely on the presence of
`documentElement.getRootNode` as iOS 10.0-10.2 supports `attachShadow` but
doesn't support `getRootNode`.
No new test is necessary - iOS 10.0 fails lots of our test suite because of
this bug.
Fixes gh-4356
Closes gh-4360
