Removed symbols which no longer exists

Source/WebCore:

This change cleans two out dated assumptions which brought in at
early stage of Shadow DOM implementation.

- Removed Element::hasShadowRoot(): shadow existence can be checked by Element::shadow().
- Made ElementShadow::removeAllShadowRoots() private: we no longer allow ShadowRoot removal.
  It can only happens at the ElementShadow destruction.

Most of changes in element implementations are basically simple
replacement from hasShadowRoot() to shadow().

No new tests. Covered by existing tests.

LayoutTests:

Removed tests cases which exercise shadow root removals.
Such functionality was only available from Internals object
and it made little sense to test it.
