Histogram total allocated bytes in the arena in addition to the render tree size

I'm a bit torn on making the bytesAllocated an out-param instead of just adding a new method to Page. It avoids some code duplication. In theory it's also faster because we only walk the frame-tree once, but I doubt that matters in practice.

Happy to change it if you think a separate method would be cleaner.

You could alternatively return a simple struct?

That's probably cleaner. Will fix.
