This should make it much easier to get a handle on one, as well as giving a per-global handle for Chrome JS. It's also handy due to LoadInfo providing a windowID in the parent process.

This will be useful as both an ID for PWindowGlobal, as well as a mechanism for taking advantage of already synchronized information. As an example, LoadInfo objects contain the inner window IDs of the window requesting the load, which can now be used to obtain a reference to the corresponding WindowGlobalParent in the parent process. Depends on D9395
