Log Message
Use the correct timebase to log scrollperf blank pixel counts on iOS
https://bugs.webkit.org/show_bug.cgi?id=143149
Reviewed by Tim Horton.
MobileSafari and WebKit need to collect scrollperf data using the same timebase;
MobileSafari can't call WTF::monotonicallyIncreasingTime(), so use CFAbsoluteTimeGetCurrent()
everywhere.
