Subject: disable optimization guide for preconnect feature

The optimization guide component
(https://source.chromium.org/chromium/chromium/src/+/main:components/optimization_guide/)
is not enabled for Electron, but the preconnect feature uses the resource prefetch
predictor code which includes this component.  This patch disables the optimization guide
component code in the resource prefetch predictor code since it is unused and including
it causes compilation problems on Windows.
