Do not delete blink::WebRTCCertificateCallback on non-main thread
blink::WebRTCCertificateCallback has a blink::Persistent, which can not
be destroyed on the original thread. However, RTC implementation brings
it to a worker thread and occasionally deletes it on that thread, in
case the main thread is already gone.
This CL replaces the deleter of the std::unique_ptr that holds
WebRTCCertificateCallback with OnTaskRunnerDeleter, which ensures the
objects is deleted on the original thread.
