Update and expand use of EuiSelectable option type generic

[thompsongl]

Summary

Fixes #3966, where the addition of a generic extension of EuiSelectableOption needed to be further propagated to all aspects of EuiSelectable and related components. More types and components accept a generic (defaulted to {}).

To aid TypeScript parsing, the id prop was more explicitly restricted (never instead of Omit, which could have been reinstated with the new generic).

Tested in Kibana with expected updates flagged
