refactor: Change TabEvent to object literal, add TabEventMap (#2191)

Add TabEventMap assiciating TabEvent types to callback signatures.
Change TabEvent to object literal so it could be used to define
TabEventMap.

BREAKING CHANGE: Delete unused event types: `openPQObject`,
`openControl`, `reload`, `clearAllFilters`.
