Low end devices should not prewarm Web process on provisional load

Reviewed by Chris Dumez.
After 266255@main, a Web process is prewarmed on provisional load instead of
when the main frame load has finished.
This is a page load time progression on most iOS devices, except for the low
end ones. For these devices, we should
still be prewarming when the main frame load has finished. The change in
266255@main is also performance neutral on
macOS, so we can also keep the original behavior there.
