Previously laid out via calls to layoutParams. This isn't as optimized
as being baked into the measure + layout system and has the issue of
being less flexible. For example, if the device profile changes (e.g.
orientation change), we'd have to apply new layout params for all the
views. With this CL, we would only need to do this for top-level views
and the children will resolve themselves.
Bug: 114136250
Test: Check layout on marlin + walleye
