[story_shell] naive implementation of original layout layout_logic

Adds the original story shell layout logic to composition_delegate:

* Surfaces with co-present relationships try to get laid out next to
  each other/.
* Surfaces with sequential relationships start a break and are shown by
  themselves on a new 'screen'
* As many surfaces as are in the focus stack are laid back on as many
  layers as required - it's up to the Presenter what to do with those

Missing from this implementation:
* Emphasis - always a strange expression, might deprecate if we can get
  reliable mod preference expression via e.g. manifest or context.
* Dependency - todo

Tests: fx run-host-tests composition_delegate_tests

Topaz

Topaz augments system functionality by implementing interfaces defined by underlying layers. Topaz contains four major categories of software: modules, agents, shells, and runners.

For example, modules include the dashboard, and runners include the Web, Dart, and Flutter runners.
