This devirutalizes a bunch of methods, and moves the entire implementation into
`Content{Parent,Child}` proper. The only purpose left for these types is as a
collection of interfaces and an IID for casting. They should likely be removed
entirely in a follow-up.

This actor won't be being used anymore, and acts only as a maintenance burden
for people working on this code (which we're doing pretty often these days!).

This commit adds a PRemoteFrame actor which is managed by PBrowser. It will
be created in a child process nsFrameLoader when loading a remote subframe.
This actor will mostly just bounce messages from a nsFrameLoader in the child
process to the actor in the parent process which will redirect the messages
to the TabParent of the remote subframe.
The piece in the parent actor to create the proxied PBrowser actors is
deferred to the next commit.

This is needed because early in a content process's lifecycle, NeckoParent may
not have been created yet. This leads to issues when trying to redirect into a
fresh process which hasn't performed network loads yet. By sending the message
over PContent, we can be sure the APIs are available.

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.

The first attempt at async launch tried to hide the asynchrony inside
IPC, by making the process seem to be launched enough to construct new
channels and send it messages, and lazily blocking on the pid/handle.
Unfortunately, in practice we wind up needing the pid/handle immediately,
and this requirement is too deeply embedded in IPC for that to be viable.
(The alternative that will be used instead -- exposing process launch via
an explicitly asynchronous promise interface -- is made simpler by
Project Fission's upcoming rewrite of how the DOM requests new content
processes.)

At the moment this isn't actually async because we immediately require
the pid and block on launch anyway. It also crashes the entire browser
on otherwise recoverable launch errors, because code that wants the pid
isn't set up to handle that operation failing.

This is based on the SharedStringMap that's currently used for shared memory
string bundles.
When the parent process is ready to launch its first content process, it
creates a snapshot of the current state of the preference database, maps that
as read-only, and shares it with each content process. Look-ups in the
snapshotted map are done entirely using data in the shared memory region. It
doesn't require any additional per-process state data.

This is the first basic implementation of a shared-memory key-value store for
JS message managers. It has one read-write endpoint in the parent process, and
separate read-only endpoints for each child-process message manager.
Changes to the parent endpoint are broadcast to the children as snapshots.
Each snapshot triggers a "change" event with a list of changed keys.
It currently has the following limitations:
- It only supports basic structured clone data. There's no support for blobs,
input streams, message ports... Blob support will be added in a follow-up
patch.
- Changes are currently only broadcast to child endpoints when flush() is
explicitly called in the parent, or when new child processes are launched.
In a follow-up, this will be changed to automatically flush after changes
when the event loop is idle.
- All set operations clone their inputs synchronously, which means that
there's no trivial way for callers to batch multiple changes to a single key
without some additional effort. It might be useful to add a
delayed-serialization option to the .set() call in a follow-up, for callers
who are sure they know what they're doing.

This class allows one read-write copy of a map in the parent process to share
data with multiple read-only copies in child processes. The maps only hold
onto data as structured clone blobs, and deserialize them each time a key is
read.
This commit only provides the bare-bones data structures. Follow-ups will add
bindings, change events, and automatic flushes.
