Previously the BrowsingContext was also being sent down, despite it being
obvious from the PBrowserBridge actor which the message was sent over.

The BrowsingContext is guaranteed to be being kept alive by
`nsFrameLoader::mBrowsingContext` and by the nsDocShell or RemoteBrowser object.
This improves the ergonomics of this helper method, which may help avoid misuse
of `mBrowsingContext`.

There are all sorts of lifecycle issues which arise from making DocShell
responsible for discarding BrowsingContexts. In this particular bug, we tend
to run into them in cases where we create a BrowsingContext for a FrameLoader,
and then never create a DocShell for it, leading to it never being destroyed.
But there are myriad other issues as well.
This patch moves the responsibility for BrowsingContext lifecycle management
to the FrameLoader/FrameLoaderOwner, rather than the DocShell, which makes
things more consistent, and more closely aligns with spec-defined behavior.

This flips the direction in which the BrowserBridge actor is generally created
such that it is generally created in the parent and sent down to a child
process.
This is done by making the decision about what kind of switch to perform in the
parent, and sending messages down to child processes async to orchestrate these
process changes.
Process launching is changed to use an async `MozPromise`-returning API in this
patch, though the actual process launching still occurs synchronously. A future
patch will enable performing async process launching through the
NewOrUsedBrowserProcess mechanism.
I know of at least a few timing issues which exist with the new logic,
especially around the state of the BrowsingContext during the process
transition. I decided to not try to fix all of these issues in this patch, as
many are complex and will require changing how we manage the lifecycle of
BrowsingContext substantially. I do, however, think that the new logic is more
reliable and has fewer timing issues than the previous logic.

This patch changes a few things about how nsFrameLoader is created, specifically
around the ChangeRemoteness API.
1. The private 'nsFrameLoader::nsFrameLoader' constructor has been simplified to
only have one overload, shared by the different `::Create` static methods.
2. The creation static method used by `ChangeRemoteness` has changed name to
`::Recreate`, as the signature is becoming more like the old method.
3. The `mNetworkCreated` bit is preserved when doing a `ChangeRemoteness`, as a
remoteness change shouldn't be affecting that property.
4. Unused fields are removed from the ChangeRemoteness API.
5. The `remoteType` attribute is now mandatory in the ChangeRemoteness API,
which simplifies the logic and makes it harder to accidentally misuse.

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.

nsFrameLoaderOwner::UpdateRemoteness will recreate the nsFrameLoader for a
piece of content. As part of this, it will unset the cached nsFrameLoader for
the content's nsSubdocumentFrame. However we need to run ShowViewer() for the
new nsFrameLoader as the frame has already been initialized. In addition,
dimensions and position on the new nsFrameLoader need to be set. Usually this
is done after a reflow, but there's no guarantee a reflow will happen after
a UpdateRemoteness operation.
