SF Bounds caching 2/3: Compute and cache layer bounds during invalidate stage
- Compute and cache:
- effective transform - transform applied to source bounds to get the screen bounds,
taking into account parent scaling and parent transforms.
- source bounds - bounds of the layer before any transformation is applied and before
it has been cropped by its parents.
- bounds - bounds of the layer cropped to its own crop as well as its parents bounds.
- screen bounds - bounds in screen space calculated by transforming the layer bounds.
- Rename existing computeBounds and computeScreenBounds to make switch easier in
future patch.
- Update cached bounds when reparenting layers for screenshots.
Note: this change doesn't use the cached values.
