4609: Fix find in page not working with fresh install r=csadilek a=VMadalin

### Description
Fixed issue: https://github.com/mozilla-mobile/reference-browser/issues/915

The `engineSession` is null on `FindInPageInteractor` because the `bind()` method set it as null via `session.engineState.engineSession`. 
<img width="752" alt="Screenshot 2019-10-02 at 08 25 39" src="https://user-images.githubusercontent.com/18151158/66025739-799e8e00-e4f7-11e9-944d-73ab86d45485.png">

Finally and after deep research I discover the problem is related with the tabs, when `EngineStateReducer.reduce()` is called for the first time no one has add the new tab created and without it it's imposible to propagate the `GeckoEngineSession` to the `BrowserState`

4600:  Closes #4289: Migrate feature-prompts to use browser-state  r=pocmo a=csadilek

This migrates our feature-prompts module to browser-state. 

@pocmo I ended up introducing `Flow.ifAnyChanged` here because returning a `Pair` or other data class instance from `ifChanged` wouldn't have worked. We're comparing for reference equality in `ifChanged` so returning a new `Pair` would always indicate change and forward the value. 

The `ifChanged` block would have to get quite complicated. We'd have to return a different instance only if changed but then we're doing all the work in the feature module and the API doesn't help us. With `ifAnyChanged` this looks quite nice and we can refine the API more later.

Most other changes are in the unit tests. I also did a round of manual testing, thanks to @Amejia481 for sending me lots of links to test :). 

I'll put up PRs for R-B and Fenix, once this one is approved.

4579: mozilla-mobile/fenix#5592 - enable private browsing for custom tabs r=NotWoods a=mohamediburan

This PR enables private mode for custom tabs (see issue mozilla-mobile/fenix#5592) where it will not track history. This PR already passed all the tests and I checked tabIntentProcessor.kt file for sample tests. So, I can update test for this. but, I didn't find any tests for verifying whether it a private or normal tab. If I need to write test cases for this, please let me know.
