This is a complete rewrite of RemoteLazyInputStream to run off of its own
toplevel protocol, rather than being managed by other protocols like
PBackground or PContent. This should improve performance thanks to no longer
needing to operate on a main or worker thread, and due to no longer needing the
migration step for the stream actor.
This also acts as a step towards no longer requiring a manager actor to
serialize input streams, as the type is now actor-agnostic, and should support
being sent over IPC between any pair of processes.

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.

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.

This is a mechanical change which was performed by a script based on the
contents of direct_call.py, and then manually checked over to fix
various rewriting bugs caused by my glorified sed script. See the
previous part for more context on the change.

Bug 1723674 added a new nsID::GenerateUUID() static factory function to generate UUIDs without the overhead of querying and instantiating an nsIUUIDGenerator object. nsContentUtils::GenerateUUID() is a utility function that amortizes that overhead by holding an nsIUUIDGenerator singleton. That's no longer necessary because code that calls nsContentUtils::GenerateUUID() can now just call nsID::GenerateUUID(). No nsIUUDGenerator is needed.

We are fixing mochitests that fail when network.cookie.cookieBehavior = 5, i.e. when we enable Total Cookie Protection.
This is most often due to the test assuming that an origin will always have access to its storage state when embedded as
a third party.
In this case I had to request storage access to allow an embedded iframe to use a BroadcastChannel to communicate with top-level pages of the same origin.
This was only a problem in the XOrigin case where the test html file is loaded in an embedded iframe and then can't communicate with the top-level window it created.

#include "mozilla/dom/WorkerScope.h" is removed from WorkerPrivate.h, where calling WorkerPrivate::GlobalScope() without include "WorkerScope.h" makes WorkerScope as an incomplete type.

This changes the test a bit. It doesn't test BroadcastChannel's postMessage anymore, but receiving the message.
I can't see how postMessage could be tested, since given the new setup, no one should have access to it anymore.
This is functionally now very similar to another test I wrote recently, but I think it is fine to keep this too.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.
5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).
