[Execution context] Add nested context support (#107523)

* Add nested context support

* remove execution context service on the client side

ExecutionContextContaier is not compatible with SerializableState, so I had to fall back to passing context as POJO. With this change, using a service looks like overhead.

* update docs

* fix test

* address comments from Josh

* put export back

* update docs

* remove outdated export

* use input.title for unsaved vis
