Crash annotations in content processes are currently sent over IPC via
shared memory buffers. To pave the way for the Rust rewrite of the exception
handler we are removing this code and gathering all the crash annotations
within the content processes themselves. This patch causes annotations to be
stored in the global table of each content process. They are then streamed
out to the parent process by the exception handler together with the
exception-time annotations.
This has a number of benefits:
* we have one less channel to exchange data between content processes and
the parent process
* we save memory because we don't need to allocate the shared memory buffers
* annotations are faster because we don't stream them all out every time one
changes
* we won't truncate annotations anymore if we run out of space in the shared
segment.
* we don't need delayed annotations anymore, so we can get rid of the
associated machinery
As I refactored the code I tried to adjust all the obsolete comments,
consolidate shared code and remove the redundant steps that were sometimes
present. In many places we had two entire crash annotation tables we merged to
change just a couple; that comes from the fact that historically we loaded
them from disk. Now it doesn't matter anymore and we can just go ahead and
change the ones we care about.

To correctly implement this, it must be known on instantiation whether E is
copy-constructible, which is not the case if only a forward declaration is
available. This can be resolved either by making sure a full definition of E is
available, which is preferable. But in cases where this is not (easily) possible,
the information can be explicitly provided by the MOZ_DECLARE_COPY_CONSTRUCTIBLE
and MOZ_DECLARE_NON_COPY_CONSTRUCTIBLE macros. In particular, declarations for
IPDL-declared types are added to nsTArray.h itself, like it was already done
for MOZ_DECLARE_RELOCATE_USING_MOVE_CONSTRUCTOR.

Splits WebGLContext into ClientWebGLContext and HostWebGLContext. The Client enables the JS-control of a WebGL context in a content procecss while the Host executes the WebGL graphics operations (via a WebGLContext that maintains much of the existing code) in the compositor process. At this point, the cross-process behavior is disabled -- this series of patches is an incremental step toward that final goal.

This patch suppresses VR device access permission prompts for users that do not have any VR runtimes installed.
We could not depend on the existing VR device enumeration functions to suppress the permission prompts, as the
act of enumerating VR devices will result in some hardware physically powering on and software starting up (and staying running)
in the background.
This patch includes logic to spawn the VR process with an additional flag indicating that it should attempt only to detect the
runtimes, without proceeding to enumerate and activate hardware and software.
VRManager now includes an enum to more clearly organize it's state machine model, which now must ensure that the runtime detection
happens on-demand when the VR session support capabilities are first determined.
There is a new pref to disable the suppression of permission prompts for use within permission UI tests on machines without VR runtimes.
Renamed some variables and added comments to make code in nsGlobalWindowInner and Navigator clearer and better represent the updated logic -- to allow the separate detection of VR runtimes and VR session activation. Both the runtime detection and VR
session activity uses VREventObserver to send events to nsGlobalWindowInner.

This changeset is a simple find and replace of `MOZ_FALLTHROUGH` and `[[fallthrough]]`.
Unfortunately, the MOZ_FALLTHROUGH_ASSERT macro (to assert on case fallthrough in debug builds) is still necessary after switching from [[clang::fallthrough]] to [[fallthrough]] because:
* MOZ_ASSERT(false) followed by [[fallthrough]] triggers a -Wunreachable-code warning in DEBUG builds
* but MOZ_ASSERT(false) without [[fallthrough]] triggers a -Wimplicit-fallthrough warning in NDEBUG builds.

This change adds the 'alwaysontop' features to the window created for FxR on PC. This is done to address issues where scrolling and entering fullscreen require the window to either be visible or have focus.

This is a dependency of the WebXR implementation.
In order to support WebXR's navigator.xr.IsSessionSupported call without
displaying any permission dialogue, it is necessary to have a safe way to
detect the capability of running a VR or AR session without activating XR
runtimes or powering on hardware.
API's such as OpenVR make no guarantee that hardware and software won't be
left activated after enumerating devices, so each backend in gfx/vr/service
must allow for more granular detection of capabilities.
By passing true to bDetectRuntimesOnly, the initialization exits early
after reporting the presence of XR runtime software. The Initialize method
will only enumerate hardware and possibly return true when
aDetectRuntimesOnly is false.

This change allows for background scripts from WebExtensions to run in the FxR on PC chrome window. In this scenario, the promise ExtensionParent.browserStartupPromise is never fulfilled because it depends on the notification sessionstore-windows-restored, which doesn't occur because the FxR window does not participate in SessionStore.
To address this issue, browserStartupPromise is now a race between the original notification and a new one, extensions-late-startup, which is fired from fxrui.js.

We should land these changes separately to enable working on WebXR features and FxR Android-side code in parallel.
