Wasted vector capacity in StyleSheetContents
​https://bugs.webkit.org/show_bug.cgi?id=224250

Reviewed by Darin Adler.

Call shrinkToFit() on the StyleSheetContents created in CSSParserImpl::parseStyleSheet()
in order to shrink m_importRules and m_childRules, which can waste about 100KB on
youtube.com.
