The lifetime of async IPDL returned promise may be longer than its actor.
That is, the handler (receiver) may have not resolve/reject the promise when the actor
is destroyed. In this case, we have to reject all the pending promises before
ActorDestroy() is called on the "sender" side.
Besides, the handler (receiver) can reject with reason "ActorDestroyed" to silently
cancel the promise without trying to reply to the remote actor which may
have died. The sender-side promise is responsible for rejecting the pending promises,
which will be done in MessageChannel::RejectPendingPromisesForActor().

The wrapper should have the same liftime as the underlying
MessageLoop. This patch use the MessageLoop's DestructionObserver to
manage the lifetime of the wrapper.

The new telemetry tag is for probing the best IPC message pre-allocate size to avoid
realloc overhead. We only count those message size which is greater than 4096.
This tag integrates IPC_MESSAGE_SIZE and MESSAGE_MANAGER_MESSAGE_SIZE2 which
have both expired.

In order to avoid a busy wait where we defer and then immediately un-defer a message,
we need to ensure that we only un-defer a message if it's actually ready to be processed.
This patch uses the same condition in MaybeUndeferIncall as we use in
DispatchInterruptMessage.

This patch implements async returns for IPDL using MozPromises. There
are following changes:
* Initialize AbstractThreads for MessageLoops
* Record promises and their reject functions
* When async message returns, call their resolve functions
* When send error or channel close, call their reject functions
* Implement "unresolved-ipc-promises" count for about:memory
* Test cases
See bug attachment for generated code from test cases

If Firefox is updated while it is running, the content process can end
up being a different version than the parent process. This can cause
odd crashes, that will happen repeatedly until the user restarts
Firefox. To handle this better, this patch adds a special build ID
message that is sent early in content process startup. The parent
process intentionally crashes if the build ID for the child process
does not match that of the parent process.

We're curious how long we spend waiting on sync IPCs to complete.
So this patch adds telemetry which reports that, on a per message
basis, so we can identify problem messages.
