This will allow experimenting with different representations of
the spatial tree (such as interning and/or providing stable
indices during display list building). It may also simplify
future changes to the public API to expose the spatial tree
directly.
As part of these changes, refactor how the debug representation
for the capture format is (de)serialized, to make it simpler to
add different payload vector types in future.

We need to track window compositor state in various cases, when compositor is paused after window creation,
when compositor is paused for hidden window (EGLSurface is missing) and paused compositor when layout is not updated yet
and drawing will lead to incorrect / obsoleted window content.
In this patch we track compositor state by WindowCompositorState atomic enum (because it can be accessed from Compositor thread)
and two private methods (PauseCompositorHiddenWindow and ResumeCompositorHiddenWindow) and two public ones (PauseCompositor() and ResumeCompositor).
Private interface is used by nsWindow when EGLSurface is missing so we can't render to window - it's initial compositor pause and
pause when window is hidden.
Public interface is used by nsWindow and WebRender compositor to disable/enable rendering when window content is updated.
When compositor is disabled by public interface it will be enabled automatically after a timeout (1s) or when content layout is updated.
Changes in the patch:
- Implement GtkCompositorWidget::RemoteLayoutSizeUpdated() to notify GtkCompositorWidget widget about layout size update in content process.
- Track nsWindow compositor state by WindowCompositorState
- Implement nsWindow::PauseCompositorHiddenWindow() and ResumeCompositorHiddenWindow() to handle internal nsWindow states.
- Implement nsWindow::PauseCompositor() and nsWindow::ResumeCompositor() to allow compositor pause/resume during content layout updates.
- Use timeout to resume compositor paused by public interface as a fallback when content is not updated or it takes too long.

Move the extra_data to be a specific cache_data separate vec in
the display list payload.
This shouldn't change any functionality, but serves as a proof
of concept for future changes which will introduce several other
separated payload vectors.

This makes it easier to understand and will make it easier to not include 'extra' frames (as we're hoping they will coalesce with the original frame on the compositor).

WebRenderBridgeParent::mPaused does not hold correct paused state, initial state of mPaused was always false. And CompositorBridgeParent already keeps correct paused state.

On WebRender there are two functions to be called for sampling animations, one is
OMTA::Sample which is called via vsync ticks in normal mode, the other is
OMTA::SampleForTesting which is called in testing refresh driver mode. The
former function is called on the sampler thread, if it gets called in between
we call nsIDOMWindowUtils.advanceTimeAndRefresh and
nsIDOMWindowUtils.getOMTAStyle AND IF the result of sampling via getOMTAStyle
was `SampleResult::None` or `SampleResult::Skipped`, we will use an incorrect
animation value via the OMTA::Sample call with the vsync timestamp, the vsync
timestamp is completely different from the value advanced by
the advanceTimeAndRefresh call.

Before we start a resource update, we should check if we are virtual
memory pressured (32-bit Windows only). If so, pre-emptively unmap
shared surfaces until the pressure is relieved to try to avoid OOMs
elsewhere. This only applies to the GPU process because the parent
process actively watches its own memory pressure and dispatches a
low-memory event which our expiration tracker is an observer for.

Whether or not we use a native texture or something else is affected by our

On 32-bit Windows, we see crashes related to running out of virtual
memory address space in the GPU process. Prior to this patch, we did not
report any memory status information from the GPU process to the parent,
only from the parent to the GPU process. Now if we go below the
threshold we request memory to be cleared in the parent/content
processes. This should trickle down to the GPU process by freeing shared
memory resources such as images, allowing us to unmap them out of the
GPU process sooner.
We will see similar problems on any 32-bit platform. The only other
target of note with sufficient numbers is 32-bit Android. There is no
GPU process on Android, however we only monitor the virtual memory
address space on Windows.

When we change the namespace, we discard all cached resources and their
associated keys from the WebRender cache. As such if any transaction
comes in with the old namespace ID, we can safefully discard the entire
update, since we will need to recreate any that we are using anyways.
This patch also adds new asserts to ensure we never get old namespace
IDs for individual keys in a valid resource update. This should never
happen in practice.

This patch adds infrastructure for crash reporter annotations to
WebRender. This is used to expose the new annotation,
GraphicsCompileShader, to indicate which shader we are in the process of
compiling. We often see crash reports when compiling shaders, and it
would be useful to know which one it is compiling.
This also adds another annotation, IsWebRenderResourcePathOverridden,
which is useful to know if someone overrode the shader resource path for
testing purposes. We can likely ignore any crash reports that have this
annotation set.
