This removes the last form of unique link between two MessageChannels so that
all MessageChannels communicate using PortLink, as it is fairly straightforward
to use PortLink to communicate between two threads in-process.

The NodeController and NodeChannel types act as the backbone connecting the
existing IPC logic and driving the ports routing code. Individual NodeChannel
objects wrap and respond to messages from IPC::Channel, and the NodeController
orchestrates all messaging for a process.
The design of these types are inspired by the types with the same names from
Mojo but have been simplified and streamlined to only support features used by
Gecko.
Support for attaching ports or handles to messages hasn't been added yet, but
can be added in follow-up patches.

The change to MessageChannel::Clear() makes mLink get cleared before
we call ~ThreadLink. This causes a race because Clear() is not
holding the monitor. To work around this, I introduced a new method
PrepareToDestroy() that handles the ThreadLink splitting. Once the
ThreadLinks are split, MessageChannel can clear mLink without a
race.
An alternative approach would be to hold the monitor in Clear()
before mLink is cleared, but then we'd end up acquiring the lock
when we didn't need to in the case where mLink is a ProcessLink.

With this change, MessageChannel stores mListener as an IToplevelProtocol
rather than a MessageListener (which isn't really a useful concept on
its own). The MessageListener methods are split out to IProtocol and
IToplevelProtocol. MessageListener gets deleted. Some of the inline
functions in MessageChannel had to be moved to MessageChannel.cpp since
IToplevelProtocol isn't defined in MessageChannel.h.

Windows messages can trigger sync ipc messages to the child process. That
means if we handle windows messages while waiting for the response to a sync
a11y ipc message we can end up reentering the code to send ipc messages which
is bad. Try and avoid this situation by not handling windows messages while
waiting for a sync a11y message.
