Some failures crept in and out after my last sets of annotations landed. This
patch updates most of the annotations to deal with them.
MANUAL PUSH: Lando won't let me land.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

When a BrowsingContext changes from being local to remote, we have to
change all window proxies from being local to remote, using
transplanting. The actual window proxy becomes a remote window
proxy. Cross compartment wrappers (CCWs) to the window proxy also
become remote window proxies in their respective compartments, rather
than CCWs to a remote proxy in the old compartment of the window
proxy, because the window is no longer actually in that
compartment. This also avoids having to figure out what Xray behavior
for remote window proxies should be.
This patch uses the transplanting support I added to
GetRemoteOuterWindowProxy() in the previous patch to ensure that the
remote proxy map holds the correct value after transplanting finishes.
It drops the requirement that both arguments to JS_TransplantObject
have the same class, because we need to transplant a window proxy with
a remote window proxy. It also deals with this by not adding origobj
to the wrapper map unless it is a CCW, to handle transplanting to a
remote proxy.
The core design here, with the remote window proxies in every
compartment, is taken from a patch by peterv.

When we call GetRemoteOuterWindowProxy in the middle of a transplant,
the remote proxy that the function returns will be almost immediately
swapped with some other object. Rather than trying to fix up the
remote proxy map when that happens, this patch adds a new argument
that is a pointer to the object, if any, that the remote proxy is
going to be swapped to. This will be used in the remote proxy map.
Having a value in the remote proxy map that is not a remote proxy
could cause issues if somebody ends up calling
GetRemoteOuterWindowProxy() a second time before the transplant has
finished. To avoid that, my patch asserts that we are returning an
object with the appropriate class.

My preference was to annotate most of the failing tests with `fail-if` so that
if they start passing, the `fail-if` needs to be removed and they need to keep
passing. That doesn't work for tests that timeout, or which trigger failures
from their cleanup functions, however, so those tests need skip-if. And tests
with fail in their cleanup functions likely leave the browser in an
inconsistent state for subsequent tests, anyway, so really should be skipped
regardless.
There are some remaining tests which still fail because of crashes. I chose
not to skip them here, but to fix the crashes in separate bugs instead.

We can remove references held in the ContentChild and the ContentParent once the BrowsingContextGroup becomes empty.
This allows to break the cycles and the BrowsingContextGroup to be deleted.

This should help us more easily identify where the crashing issues are coming
from. The issue in part 1 was found due to these assertion changes.

This ensures that the object is not discarded while there are still in-flight
messages from the parent process, and vice-versa, which could cause crashes if a
CC was run before any pending messages have arrived.

We shouldn't perform an anti-tracking check here, since that may result
in us picking the node principal unintentionally.
