Add the test for Shadow-DOM ::distributed() pseudo-element with Relative selector.
The only first <shadow> element is used when the shadow tree has multiple <shadow> elements. Original tree's node is not inserted into the second <shadow> element.

Update the test of ShadowDOM::distributed() pseudo-element
shadow-dom: Improve the readability of two basic reftests.

This change updates two basic reftests in the shadow-dom directory to make
them easier to understand. The new tests are intuitive (green is pass and
red is failure), and has a sentence explaining the passing condition.

This change also fixes some style issues. Most notable error was the name of
link type for reference ("reference" is wrong; "match" should have been used).

i.e.
div::x-thumb > span  style does not apply <div><span></span></div>.
above then the specified x-thumb pseudo in the tag.
