Perf: Incremental culled shapes calculation. (#3411)
Reworks our culling logic:
- No longer show the gray rectangles for culled shapes. 
- Don't use `renderingBoundExpanded`, instead we now use
`viewportPageBounds`. I've removed `renderingBoundsExpanded`, but we
might want to deprecate it?
- There's now a incremental computation of non visible shapes, which are
shapes outside of `viewportPageBounds` and shapes that outside of their
parents' clipping bounds.
- There's also a new `getCulledShapes` function in `Editor`, which uses
the non visible shapes computation as a part of the culled shape
computation.
- Also moved some of the `getRenderingShapes` tests to newly created
`getCullingShapes` tests.

Feels much better on my old, 2017 ipad (first tab is this PR, second is
current prod, third is staging).
