Previously, we created TextureD3D11 objects in the content process to back surfaces created for the plugin process. Those objects were then composited by the async ImageBridge. In order to remove Win32 kernel operations from content (including DX/GDI operations), this patch bounces the requests from content to the compositor process. The compositor process maintains 2 textures to be used for all plugin composition -- one for the plugin process and one for display. The plugin process can freely write to its texture and request composition when it is done, which triggers a blit to the display texture. This mirrors pre-existing behavior.

These operations report whether certain async plugin drawing modes are supported on the host architecture. They use kernel graphics operations to decide this so they need to be removed from the content process for sandboxing. We just bounce the requests to the gpu process (or main process on systems without a GPU process).

`windowUtils.setCompositionRecording()` now returns a promise that is resolved
when the composition recorder is enabled (if given `true`) or when frames are
written to disk (if given `false`). To accomplish this, the
`WebRenderCompositionRecorder` now returns a `MozPromise` when writing frames
to disk begins that is resolved when that process finishes.

Inside of nsDocShell::UpdateURLAndHistory, there are 4 sync IPC calls to
nsSHistory plus 1 static call, which contains at least one nsSHEntry::GetParent
sync IPC call. All of these calls can be moved inside of a new method
EvictContentViewersOrReplaceEntry on nsSHEntry, resulting in just 1 sync IPC

method to parent process for nsISHEntry, resulting in a new method
nsISHEntry::GetChildSHEntry, 3 sync IPC calls can be reduced to 1.

In nsDocShell::LoadHistoryEntry method, when it gets called
from parent process, there are 13 sync IPC calls on nsISHEntry
that retrieve information from the session history entry and
create a doc shell load state object using the retrieved
information. By adding a new method 'CreateLoadInfo'on nsISHEntry,
inside of which the doc shell load state object will be
created (with appropriate data filled out) and returned,
we eliminate 12 sync IPC call, resulting in just 1 IPC call
to nsISHEntry::CreateLoadInfo.

Currently, nsDocShell repeatedly calls nsISHEntry::GetChildAt and
nsISHEntry::RemoveChild in nsDocShell::AddToSessionHistory,
which results in twice as many IPC calls as the number of children
a session history entry has. Additionally, there is one extra
IPC sync call to nsISHEntry::AbandonBFCacheEntry after the loop.
With the proposed solution, there will only be 1 sync IPC call.

This takes the approach of directly tying the `AddRef()` and `Release()` calls
on the underlying actor object to the lifecycle of the ActorLifecycleProxy
object, by adding another virtual `ActorAlloc()` method as the counterpart to
`ActorDealloc()`.
The changes to the methods called from C++ are relatively minimal:
1. The `SendPFooConstructor(...)` methods have the same signature, but now will
AddRef() internally (through `ActorAlloc()`), so an `do_AddRef(foo).take()`
isn't needed. Same with the `{Bind,Open}PFooEndpoint` methods.
This was done to reduce the number of invasive internal changes in the
codegen which were required to pipe a passed-in `already_AddRefed` to the
underlying `ActorLifecycleProxy` which is created by generic code.
2. The `AllocPFoo{Parent,Child}` methods have been modified to return an
`already_AddRefed` by default, and the callsites will store the result in a
`RefPtr<T>` if the type is refcounted.
3. No `DeallocPFoo...` method is called anymore. Unfortunately due to
devirtualization, it won't be an error if an unused method is still present,
though it won't be called.

The previous behaviour of failing unconditionally was performed as, during
shutdown, the channel could become unable to send without worker threads having
a chance to react. This change keeps that behaviour, isolating async message
senders from impending IPC shutdown, while performing expected actor teardown if
the manager actor has already been destroyed, and should no longer send messages.
An alternate behaviour here could be to crash if !Manager()->CanSend(). That
behaviour may be preferable if a sufficient number of callsites don't check the
return value of the `SendPFooConstructor()` method.

The vast majority of the virtual methods which were used on ProtocolState were
actually methods which only had meaningful implementations on the toplevel
protocol. This patch adds a new field to IProtocol holding a direct pointer to
the protocol's `IToplevelProtocol`, and the methods formerly implemented with
ProtocolState now directly call the corresponding method on IToplevelProtocol.
IToplevelProtocol then shadows these methods with the toplevel protocol
implementation, meaning that the right code is run in the right places.
In addition, some state was maintained for protocols inside of the separate
ProtocolState allocation, and this patch moves that state back into the actor
itself.
