Saved objects: improve typesafety (#140099)

* Remove SavedObjectAttributes from examples

* Remove SavedObjectAttributes from dev_docs

* Deprecate SavedObjectAttributes type

* Remove SavedObjectAttributes from kibana_usage_collection plugin

* Remove low hanging SavedObjectAttributes in security_solution

* Remove low hanging SavedObjectAttributes in upgrade_assistant

* Remove low hanging SavedObjectAttributes in lens

* Stricter types for SavedObjectsServiceSetup.registerType

* Review feedback

* Some more low hanging fruit
