By passing the startTime as a TimeDuration we are able to represent times in the
distant past (and with the same range as we can represent on the main thread so
that if we do encounter range errors in future, they should not differ between
the main thread and the compositor).
This patch includes a crashtest. I have verified that, without the code changes
included in this patch, this crashtest fails on debug builds on OSX.

In bug 1223658 we separated out the delay from the start time but we failed to
remove it from this calculation. As a result, when a pending animation begins it
will have the delay applied twice (once here, and once when it is sampled on the
compositor). This will happen until the layer is next updated.
This bug was not exposed by any existing tests since we don't use this code path
when the refresh driver is under test control. Furthermore, the one test that
was supposed to cover this was refactored in such a way that it stopped testing
this code path. That test is restored earlier in this patch series and enabled
in this patch.

PLayerTransaction's constructor was previously synchronous so we could
return a TextureFactoryIdentifier. This is quite reliably available
already in the case of opening a tab, due to RenderFrameParent knowing
which compositor it is attached to, so we can make the constructor
asynchronous.
In the top-level widget case, we add a new synchronous message to find
the TextureFactoryIdentifier.
Because ProfilerMarkerPayload is the main type defined in these files, and
because the next patch is going to introduce ProfilerMarker.{h,cpp}, which
would be confusingly similar to the old names.

The MultiTouchInput::MULTITOUCH_END generated from transitioning from
multiple touch sources to a single source would often cause the content
to shift under the remaining finger which would look like a fling and
cause the content to rapidly scroll. This patch treats the transition from
multiple touch source to a single source as if the touch event were
starting over by resetting all the variables tracking the touch drag
that is in progress.

Since tabs are loaded and shutdown asynchronously with respect to the UI
process, it is possible for a tab to be loading as its parent widget and
compositor are shutting down. We protect PAPZCTreeManager's constructor
against this by making a temporary APZCTM object.

This is functionally equivalent since one variant of the
PushStackingContext was already delegating to the other (in
DisplayListBuilder).

This class is a RAII class that can be used to push a stacking context
with properties from a WebRenderLayer. It can also then be used to
convert rects in the layer coordinate system to be relative to the
stacking context, which is what we want for passing to WR.
