Revert "Move OpenURL from RenderView to RenderFrame."

This reverts commit e0dd068fdd87221bdd30c99c380835038f804f07.

Suspected of causing layouttest failures. Specifically, some are
timing out, and some are no longer printing messages like:
Policy delegate: attempt to load http://127.0.0.1:8000/misc/resources/iframe-policy-2.html with navigation type
'link clicked'

e.g. http/tests/misc/policy-delegate-called-twice.html
