Let Position-based findPlainText return Positions as results.

blink::TextFinder uses findPlainText() function to search text. To be able to
search a page containing Shadow DOM properly, it needs to use Positions,
instead of Range, for the document range to be searched and for ranges of
text found.

This patch makes Position-based findPlainText() return the range of text found
as Positions instead of Range, as a step toward fixing find-in-page with
Shadow DOM.

Refactoring only; behavior should not change.

Fix use-after-free in BreakingContext.

BreakingContext was holding a raw pointer in m_currentStyle, but it calls layout during handleFloat(), and FastTextAutosizer assigns a new RenderStyle during layout.  (We can't mutate the existing RenderStyle due to style sharing.)

To ensure that raw pointers to the RenderStyle are safe during layout, FastTextAutosizer now keeps a RefPtr to the previous style until the end of layout.
