adding [Add]EventListenerOptions parameter for generated signatures

For the signatures generated within TS.fsx:
* Changes the type of the third argument to `boolean | AddEventListenerOptions` for `addEventListener`
* Changes the type of the third argument to `boolean | EventListenerOptions` for `removeEventListener`

Additionally, there were a few changes in addedTypes.json that needed to be updated by adding `removeEventListener` signatures and updating both `addEventListener` and `removeEventListener` to allow options:
* BroadcastChannel
* IDBDatabase
