Reviewed by Alexey Proskuryakov.

Adding a property to check whether this ResourceError was raised due to a timeout.
This is preparatory work for bug 74802. In order to implement XHR2 timeout functionality,
I need to identify some layers up whether the original network problem has been a timeout.

No new tests, no change in behavior yet.
