Align some set innerText behavior with standard

According to spec[1], when a string starts with CR/LF set as innerText,
the first child node should not be an empty text node. So we adjust the
logic in HTMLElement::TextToFragment to make sure it follows the spec.

Besides, same in spec[1], there is no special procedure for setting
innerText when the element is being rendered and styled as preserving
new line, so corresponding code was removed in this commit.

15 failed wpt tests could be passed after this change.
