Original issue's description:
> Reland #1: IPC: Add attachment brokering support to the message header.
>
> This reland fixes a race condition in the unit test SendHandleTwice that caused
> the test to flakily fail, mostly on XP machines. This reland also updates switch
> statements to contain a block for the newly added enum
> BrokerableAttachment::PLACEHOLDER, which was causing problems with the clang
> Windows build.
>
> > Message dispatch happens before message translation, and message dispatch
> > requires that all brokered attachments have been received. This means that
> > attachment brokering needs to function without message translation. This is
> > accomplished by modifying the message header to include a new field
> > num_brokered_attachments, and writing the attachment ids into the IPC Channel
> > immediately following the pickled message itself.
> >
> > AttachmentBrokerPrivilegedWinUnittest was expanded to test ChannelReader in the
> > receiving process. It is now a fully functional end-to-end test of attachment
> > brokering.
