1899509 - Off-main-thread RemoteWorker initialization

Status: ASSIGNED

(Core :: DOM: Workers, enhancement, P2)

Description

[Eden Chuang[:edenchuang]]

This is part of bug 1672491. This bug is specific to make RemoteWorker initialization in WorkerPrivate::Constructor() be off-main-thread.
For more details, WorkerLoadInfo initialization for the top-level worker must be on the main thread. Still, these data can be obtained from RemoteWorkerData through IPC for ServiceWorker/SharedWorker, which does not need to be initialized on the main thread and can be done on the Worker Launch thread.
