Nika Layzell bdb401316d Bug 1908725 - Part 2: Make the ChildID available in the same places as OtherPid, r=ipc-reviewers,media-playback-reviewers,win-reviewers,alwu,rkraesig,gfx-reviewers,mccr8,nical
This requires quite a bit of piping to get the ChildID passed everywhere where
we currently pass the pid in IPC. This is done by adding a new struct type
(EndpointProcInfo), which is passed around instead of OtherPid in these places,
and contains the full pid.

In most cases, it was a fairly painless change to move over, however in some
cases, more complex changes were required, as the pid was being stored
previously in something like an Atomic<...>, and needed to be switched to using
a mutex-protected value.

In the future, it may be possible to remove OtherPid from IPDL actors once
everything is migrated to ChildID, but we're still a long way off from that, so
for now we unfortunately need to pass both around.
