New IPC PRemoteWorkerDebuggerManager and PRemoteWorkerDebugger are introduced to support remote debugger of Workers on the parent thread. PRemoteWorkerDebuggerManager is IPC between the parent process main thread and the content process WorkerLauncher thread. PRemoteWorkerDebuggerManager is used to handle the remote debugger registration. PRemoteWorkerDebuggerManagerParent/Child binding happens when creating RemoteWorkerService for a new process. PRemoteWorkerDebuggerManager IPC binding implementation is in P2. PRemoteWorkerDebugger is IPC between the parent process main thread and the content process Worker thread(directly dispatch to DebuggerQueue) PRemoteWorkerDebugger handles the communication between the remote debugger and the worker(DebuggerGlobalScope). PRemoteWorkerDebugger also handles the remote debugger unregistration. RemoteWorkerDebuggerParent is an nsIWorkerDebugger object that cooperates with WorkerDebuggerManager in the parent process. Basically, we keep the original debugger registration logic for the remote debugger. The worker parent thread() is still blocked, but not by the main thread. The detailed implementation is described in P3. Differential Revision: https://phabricator.services.mozilla.com/D230259
