As serializing IPCStream no longer requires a manager or FileDescriptor array,
the arguments are no longer necessary, and can be removed. The AutoIPCStream
helper can also be removed, as managed actors are no longer used for
serialization, so a delayed start callback is not necessary.

The delayed start parameter is also removed from nsIIPCSerializableInputStream
instances, but is still present as `aAllowLazy` on the toplevel serialization
methods.

This interface should no longer be required due to the changes in part 1
limiting the complexity of IPCStream instances and limiting the number of file
descriptors which a single stream can attach to a message.

Removing this interface is necessary to serialize nsIInputStream instances over
arbitrary toplevel protocols and non-protocol IPC in the future.

Bug 1754004 - Part 1: Switch IPCStream to use DataPipe instead of P{ChildToParent,ParentToChild}Stream, r=asuth,necko-reviewers,kershaw

This gives us various positive benefits, such as using a shared memory ring
buffer for faster communication, not having data streaming being bound to the
thread which transferred the nsIInputStream (which is often the main thread),
and the ability for some backpressure to be applied to data streaming.

After this change, the "delayed start" parameter for IPCStream serialization is
less relevant, as backpressure will serve a similar purpose. It will still be
used to determine whether or not to use RemoteLazyInputStream when serializing
from the parent process.

Differential Revision: https://phabricator.services.mozilla.com/D77575

Before this change, the collection of typedefs to include in IPDL
protocols was being performed in the _DecorateWithCXXStuff pass of
lower.py. This pass iterates over all included headers, including
recursively, so will also visit headers included by headers you import.

The recursive behaviour caused issues because importing and
forward-declaring imported types is non-recursive, looking at exported
types only one layer deep. This could lead to typedefs being generated
in IPDL protocols referencing types which could never be named by the
IPDL code, and which had no definition in c++, leading to build errors.

This patch changes the logic to instead happen during the
_GenerateProtocolActorCode pass of lower.py, which is also where
required forward declarations and imports are handled, allowing us to
keep the set of typedefs generated more tightly in sync with the actual
set of types available to the actor.

This required some changes in client code which was relying on
incorrectly generated typedefs, however these types have now been fixed.

Bug 1751948 - Part 7: Fix non-unified filename conflict between generated and non-generated ChannelInfo.cpp files, r=asuth

Due to the earlier changes in this patch series, we now build IPDL files
within the directories which they're declared in, meaning that the
generated ChannelInfo.cpp file made by ChannelInfo.ipdlh will try to
compile a ChannelInfo.o file on top of ChannelInfo.cpp's ChannelInfo.o
file when building in non-unified mode.

This works around the issue by renaming the ipdlh file to
IPCChannelInfo.ipdlh.
