Source/WebCore:

Element::shadowRoot() was used for these 3 purposes.
1. checks a shadow root exists.
2. gets author shadow root.
3. gets user agent shadow root.

We have to distinguish them when implementing multiple shadow subtrees.

Calling for (1), (2), and (3) are convered to hasShadowRoot(),
ShadowRootList()->youngestShadowRoot(), and ShadowRootList()->oldestShadowRoot() respectively.

No new tests, no change in behavior.
