In this patch, IPC PRemoteWorkerNonLifeCycleOpController is created for non-life cycle operations of SharedWorker/ServiceWorker. PRemoteWorkerNonLifeCycleOpController is the IPC between the content process worker thread and the parent process background thread. This IPC helps to build a direct communication instead of go through worker launcher thread and the main thread. Endpoint<PRemoteWorkerNonLifeCycleOpControllerParent/Child> pairs are created when RemoteWorkerManager::LaunchInternal(). The parent Endpoint is binded a RemoteWorkerNonLifeCycleOpControllerParent immediately and connect to the corresponding RemoteWorkerController. And the child Endpoint is passed through IPC PRemoteWorkerService::SendPRemoteWorkerConstructor() to the content process, and then binds to a PRemoteWorkerNonLifeCycleOpControllerChild when the Worker gets into "Running" state. After connection is built, RemoteWorkerController can send non-life cycle related operations by PRemoteWorkerNonLifeCycleOpController and send life cycle related operations by PRemoteWorker. Depends on D196946 Differential Revision: https://phabricator.services.mozilla.com/D197563
