Don't run the prerendering tests that verify prerendering is cancelled for cross-process navigations under PlzNavigate.

Prerendering has these tests since it requires only one render process is used for prerendering. Without PlzNavigate, it detects a cross-process navigation and cancels prerendering. However with PlzNavigate, this scenario doesn't exist since we only determine the (one) render process to use for prerendering after redirects have been followed.

This fixes
PrerenderBrowserTest.PrerenderCrossProcessServerRedirect
PrerenderBrowserTest.PrerenderCrossProcessServerRedirectNoHang
with PlzNavigate.
