- `registerCommandListener` documentation was wrong so that is fixed
- use `uniqueIdProvider` much as possible so we are not duplicating logic
- add `appRegistryService` which makes `componentRegistry` cleaner and also makes testing easier
- type return type of `NativeEventsReceiver.ts` correctly
- add types to `LayoutTreeParser`
- `ComponentRegistry.test.tsx` refactor so it tests only things that is should and not implementation of React Native functions
- fix type `center` prop to be required on `LayoutSideMenu`
- add missing layout props `topTabs` and `externalComponent`
- lots of minor cleaning

## Goal of this PR
The goal of this PR is to make `OptionsProcessor.ts` great again 🇺🇸 . To me it was total mess including tests. 

## What was wrong or funky?
1. the tests tested if React Native's `processColor` color works as it should even though react native has [multiple tests for this](https://github.com/facebook/react-native/blob/master/Libraries/StyleSheet/__tests__/processColor-test.js). Aka we don't have to test React Native's functions :D
2. `LayoutTreeCrawler.test.ts` was testing `OptionsProcessor`s functionality so it was removed now
3. Lots of small things since this was done before putting `noImplicitAny` to true so it wasn't made TypeScript in mind

## Result
Now `OptionsProcessor.ts` should be
1. code way more clear
2. tests are testing only things that they should
3. tests are written in clear way
4. it is easy to see from the tests what the whole function does
5. type safe for TypeScript `noImplicitAny` (when we actually turn it on)

This PR adds support for setting stack root with multiple children, which is to be expected as stack can be initialised with multiple children.
Closes #4441

Increase type safety in 3 most important files

RelativeLayout rules caused excessive CPU usage due to issues with RN's
keyboard detection mechanism (based on global layout listener)

I clarified some of the language here so that it is easier for the beginner to understand. (It was a little bit awkward before)

* Increase gradle daemon process memory

* Disable Orientation test on Android

* Fix SideMenu e2e

* Fix popTo

* Use margin instead of RelativeLayout rules to align component to BottomTabs

Rules caused excessive CPU usage due to RN issue with global layout listener
and keyboard visibility detection.
