Combine script profiling with profile crates. Fixes#7514.
The script crate had its own built-in profiling which was basically doing the same thing as the profile crate. This wraps the internal profiling around the main profile functionality. Script-related tasks are now added to the ProfilerCategory enum.

Have PaintLayers own StackingContexts instead of the opposite
Previously, StackingContexts might have a PaintLayer. We switch the
ownership, for several reasons:
* We want PaintLayers to potentially contain something other
than a StackingContext soon.
* We want to delay the creation of PaintLayers until the last
minute, so that we can synthesize new layers for sandwiched
content.
This commit also implements the second goal. Instead of creating
PaintLayers during layout itself, wait until we are sorting and
layerizing a completed DisplayList.
