After the part 1 fix, we can still (asynchronously) call some generic cleanup
code that tries to let the parent process's RemotePrintJobParent know that
printing failed under the stack:
RemotePrintJobChild::OnStatusChange
nsPrintData::DoOnStatusChange
nsPrintJob::FirePrintingErrorEvent
nsPrintJob::CleanupOnFailure
We crash on trying to use the RemotePrintJobChild to message the parent process
since the delete message from the parent has been processed. This change makes
RemotePrintJobChild::OnStatusChange check that it's initialized before trying
to send any messages.
Pushing to CLOSED TREE since this passed a full Try build and is a topcrash
we want to land for beta ASAP.

If in the future nsDeviceContextSpecWin::BeginDocument was to return
NS_ERROR_FAILURE, then the channel between RemotePrintJobParent and
RemotePrintJobChild will be close at [1]. RemotePrintJobChild keep using ipc
calls after the channel is broken and hits assertions.
PS:
We always hits this assertion by forcing nsDeviceContextSpecWin::BeginDocument
returning NS_ERROR_FAILURE. It's not relative to the change we made in
previous patches.

With this patch print IPC no longer requires the child process to create files.
Instead files are opened by the parent and a file descriptor is sent to the
child. This will allow us to sandbox child processes more aggressively.

This function is arguably nicer than calling NS_ProcessNextEvent
manually, is slightly more efficient, and will enable better auditing
for NS_ProcessNextEvent when we do Quantum DOM scheduling changes.
We will use the new type for the generated IPDL message handler
prototype to make sure correct error handling method is called.

Adds a new timer for the RemotePrintJob to notify the nsPagePrintTimer when the last page has finished printing in the parent.
Changed the page delay timer to reset the watch dog count on every page to prevent timeouts due to remote printing.
