Add a new test for checking rounding error in printing codes
https://bugs.webkit.org/show_bug.cgi?id=61256
Add a new test (printing/page-count-with-one-word.html). This test
checks if only one page is printed for an HTML page with one word for
various paper sizes around A4 portrait size, i.e. [530px, 560px) for
width and [730px, 760px) for height.
* printing/page-count-with-one-word-expected.txt: Added.

Add resizePageRectsKeepingRatio(), which expands/shrinks a page, keeping the ratio of the original page
https://bugs.webkit.org/show_bug.cgi?id=61256
In order to prevent rounding error caused by expanding/shrinking a page
using different calculation here and there, I added a common calculation
method, resizePageRectsKeepingRatio(), which expands/shrinks a page,
keeping the ratio of width and height of the original page.
PrintContext::computePageRects() and PrintContext::begin()
use resizePageRectsKeepingRatio() to expand/shrink a page.
