When EGL_LOSE_CONTEXT_ON_RESET is set by CreateContextFlags::PREFER_ROBUSTNESS flag, ANGLE avoids to release D3D resources when ANGLE detects device reset. It is necessary to avoid nullptr dereference in ANGLE.

This will allow use of the DirectComposition virtual surface API. If
it turns out that some pages recreate surfaces a lot due to opacity
changing, we can add some extra logic to avoid recreating surfaces
as often, and making use of per-tile opacity in some cases.

The only reason BufferTexture needs a LayersIPCChannel instead of the IShmemAllocator base interface is that it needs to know if the allocator is cross-process or not. Both LayersIPCChannel and ISurfaceAllocator use IsSameProcess() for this but without a common interface for it. Rather than further complicate the inheritance diagram for the layers and IPDL core classes, this patch makes BufferTexture handle both with generic code.

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.

I'm not quite familiar with the history of this code, but Gnome a11y settings
set the scale to 1.25 (which gives 120dpi). We were rounding it away, which

Suggestions for a better name than "snapshotter" are welcome.
This is a separate object so that the lifetime of its GLContext isn't governed by the lifetime of the NativeLayerRootCA.
The NativeLayerRootCA gets destroyed on the main thread, but GLContext uses non-threadsafe weak pointer support, so it wants to be destroyed on the same thread that it was created on.
So now the GLContext lives on the snapshotter, which is created and destroyed on the renderer thread.

When one uses SourceSurfaceRawData to wrap a data pointer, it will
perform a copy of said data if GuaranteePersistence is called. This is
done for DrawTargetCapture, which is used with OMTP. Prior to this
patch, image surfaces would be wrapped by a SourceSurfaceRawData when
using the basic compositor on any non-Linux platform (since Linux does
not support volatile memory). This means every time imgFrame::Draw is
called with OMTP, a copy of the image will be made. Images don't need
this property since the data is already going to persist, so this patch
adds a new class SourceSurfaceMappedData, which takes a ScopedMap
keeping the underlying surface open and readable.
