Previously, internals.isPreloaded() depends on |ResourceFetcher::m_preloads|,
which is cleared by ResourceFetcher::clearPreloads().
This caused internals.isPreloaded() to turn false after around document's
load event.

This CL makes ResourceFetcher to keep a set of preloaded URLs (separately
from |m_preloads|) if a blink::Internals object is created, and use the set
to calculate internals.isPreloaded().
