Support a module API surface for custom functionality (#8246)

* Early implementation of module API surface + functions for ILAG module

* Wire up dialog functions and ILAG-needed surface

* Ensure component renders for modules get overridden

* Respond to changes from module API interface

* Use a real module-api dependency

* Update for new Dialogs interface

* Add support for getConfigValue from module API

* Update the remainder of the module API interface

* Docs & cleanup

* Add some unit tests around module stuff

Needs end-to-end tests still.

* Appease early linters

* Break import cycles by not directly depending on Lifecycle

* Appease the linter

* Fix bad merge
