This improves consistency with the child process case, and will make it easier
to attach additional state without needing to thread it through every child
process callsite manually.

In the following patch we are going to change the signature of
ShouldSanitizePreference to take a Pref object. Pref is only
known to the Preferences compilation unit; so to keep this member
(whose signature will change) we would need to expose the Pref
class. However it will only be a forward declaration, one could
not construct a Pref object in e.g. the gtest.
It is simpler to just remove the member entirely and call
ShouldSanitizePreference unconditionally - the member was only
used for the gtest, and while the gtest will be less robust
because of this change, it will still do some testing.

To do the correct thing in Preferences::SerializePreferences

the destination process is a web content process or not.
We add parameters to

In Preferences::SerializePreferences we fix the call to

`base::KillProcess`, with the `wait` parameter set to true, does a
bounded blocking wait for the process to exit by polling and sleeping in
a loop, with ad-hoc parameters. The only user of that case is the Gecko
Media Plugin code, which doesn't actually need it as discussed in bug
(comments 4-6); also, currently it's blocking the IPC I/O thread in the
parent process, which is not good for browser responsiveness.
Accordingly, this patch deletes that code and removes the parameter.

Add a function to GPUProcessManager to force the GPU process to crash,
and expose it through gfxInfo. Expose this to geckoview tests via the
test-support webextension.
Add a junit test GpuCrashTest, which triggers a GPU process crash and
ensures the crash reporter was notified.
Additionally, ensure the TestCrashHandler service is stopped in
between tests, as otherwise only the first crash test to run will be
notified of the crash.

GPU process crash reports are handled by calling GenerateCrashReport()
in GPUChild::ActorDestroy() if the reason is AbnormalShutdown. This
ensures we only create crash report if the process actually crashed,
and not when it was deliberately stopped.
However, sometimes actors other than GPUChild are the first to be
destroyed immediately after a crash, for example CompositorBridgeChild
or UiCompositorControllerChild. If such an actor receives an
ActorDestroy message with AbnormalShutdown as the reason, they will
call GPUProcessManager::NotifyRemoteActorDestroyed(), which leads to
GPUProcessHost::Shutdown(), which will close the PGPU channel. This
creates a race condition after a GPU process crash, where sometimes
the channel gets closed gracefully and ActorDestroy will receive a
NormalShutdown reason rather than AbnormalShutdown.
This patch adds a flag to GPUProcessHost::Shutdown() indicating
whether it is being called in response to an unexpected shutdown being
detected by another actor. If set, it sets a flag on the
GPUChild. When GPUChild::ActorDestroy() eventually gets called, it
knows to act in response to a crash if either the reason is
AbnormalShutdown or this flag has been set.

Declare a GPU process and corresponding Service in the
AndroidManifest. This is of a new class GeckoServiceGpuProcess which
inherits from GeckoServiceChildProcess, and provides a binder
interface ICompositorSurfaceManager which allows the parent process to
set the compositor Surface for a given widget ID, and the compositor
in the GPU process to look up the Surface for a widget ID. The
ICompositorSurfaceManager interface is exposed to the parent process
through a new method getCompositorSurfaceManager() in the
IChildProcess interface.
Add a new connection type for GPU processes to GeckoProcessManager,
along with a function to look up the GPU process connection and fetch
the ICompositorSurfaceManager binder. When the GPU process is launched
we store the returned binder in the GPUProcessHost, and when each
widget's compositor is created we store a reference to the binder in
the UiCompositorControllerChild.
Each nsWindow is given a unique ID, and whenever the Surface changes
due to an Android resume event, it sends the new surface for that ID
to the GPU process (if enabled) by calling
ICompositorSurfaceManager.onSurfaceChanged().
Stop inheriting AndroidCompositorWidget from InProcessCompositorWidget
and instead inherit from CompositorWidget directly. This class holds a
reference to the Surface that will be rendered in to. The
CompositorBridgeParent notifies the CompositorWidget whenever it has
been resumed, allowing it to fetch the new Surface. For the
cross-process CompositorWidgetParent implementation it fetches that
Surface from the CompositorSurfaceManagerService, whereas the
InProcessAndroidCompositorWidget can read it directly from the real
widget.
AndroidCompositorWidget::GetClientSize() can now calculate its size
from the Surface, rather than racily reading the value from the
nsWindow. This means RenderCompositorEGL and RenderCompositorOGLSWGL
can now use GetClientSize() again rather than querying their own size
from the Surface.
With this patch, setting layers.gpu-process.enabled to true will cause
us to launch a GPU process and render from it. We do not yet
gracefully recover from a GPU process crash, nor can we render
anything using SurfaceTextures (eg video or webgl). Those will come in
future patches.

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.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.
