nsITabParent is exposed to frontend code and is generally used as a representation of a remote tab. We could just rename the interface to nsIBrowserParent and worry about it later, but I think it's better to rename the interface to nsIRemoteTab so that we can later work on splitting the interface away from the PBrowser protocol.
Note: Some frontend code refers to a TabParentId. This commit renames this to RemoteTabId. We need to figure out the purpose of TabId with fission.

This adds a single new method, which acts like sendAsyncMessage, but
also returns a promise. This promise is fulfilled when the promise
returned from the receiveMessage callback is resolved.
```
partial interface JSWindowActor {
[Throws]
Promise<any> sendQuery(DOMString messageName,
optional any obj,
optional any transfers);
}
```

When a remote type mismatch is found for a subframe, this patch checks if
fission is enabled for that window. If it is, it triggers a process switch,
continuing the load in a new process.
With this patch, subframes will only change process when navigating to a HTML
subframe, and not when navigating to a non-HTML subframe. That will be fixed in
a follow-up. This patch also does not change the remote type selection logic,
so only very limited types of remote iframes are supported.

This patch takes the approach of taking a reference, so that we can land
it into the tree more quickly & fix issues we have.
This isn't a final solution by any means, we should also do something
along the lines of the StableState approach, but it should be sufficient
for now.

For cases where the class has direct calls (that is, we cast `this` to the
subclass before making the call) no longer declare Recv/Answer methods on the
base class at all. This should ensure that slots for them are not generated in
vtables, and also allow the derived class to choose the method signature (e.g.
whether it wants to take something by reference or by value).

When calling a Recv/Alloc/Dealloc method on most types, cast `this` to the
derived class.
There is a heuristic to figure out what the correct derived type is. There is a
blacklist of types which we can't do direct calls on for the moment, as well as
an override for types that do work with direct calls but which don't match the
heuristic.

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.

This serves 2 purposes:
1. Provides an object corresponding to an inner window which Chrome JS can hold onto.
2. Provides the object to JS which Chrome JS per-window actors will be attached to.
3. Provides useful information to Chrome JS in the parent process.

This allows getting the set of all window globals for a given browsing context.
This is less useful at the moment as the active window global is not exposed as
such. That will be added as a follow-up.

This actor can be used for communicating with individual frames, without
depending on walking the tree in the content process.
This is not yet complete. No tests have been written for it, the
WindowGlobalParent objects need to be exposed to chrome JS, and a form of JS
actors should be installed under them.
In addition, BrowsingContextChrome objects should be updated to allow access to
the current WindowGlobalParent in that context.
