This reverts commit 0b48266711.
Reason for revert: Causes widespread flakiness in http/tests/devtools
web tests. see crbug.com/329487276 for one example bug with links to
test histories.
Original change's description:
> Update test runner to account for same-site RFH change
>
> With RenderDocument, we can change RenderFrames within the same
> process. This is not currently handled correctly by some parts of the
> WebTestControlHost. This is fixed by this CL by:
> - Making WebTestWindowObserver observe pre-existing speculative RFHs
> (it would miss them otherwise since those already called
> RenderFrameCreated before the construction of WebTestWindowObserver)
> - Making WebTestControlHost call ReplicateWebTestRuntimeFlagsChanges
> on all WebTestRenderFrameRemotes instead of only one per renderer
> process (as there can be multiple)
>
