Now that BottomTabs options are applied on self, they need to be cleared after applying initial options.

Relying on WRAP_CONTENT caused rare bugs where the TopBar would appear stretched due to flex issues
when a react component was displayed in the title.
Another reason for this change is that we don’t need to wait for the TopBar to measure itself when its height needs to be taken
into account, for example when animating it or when positioning views below it.

* Fix ability to add color for back button

* Change docs because color can be used with iOS too

* Simplify code more

* Move icon logic to one function

* Make returning more clear

* Remove title setting because it is in setBackItem

* Make setBackItem function more clear

* Looks like the if is not needed

* Update RNNBackButtonOptions.m

* Update RNNBackButtonOptions.m

* Renamed RNNRootViewProtocol to RNNParentProtocol and added RNNLeafProtocol

* fixed unit test

* Better options resolving

* Merge stack options

This commits adds support for merging stack options by the stack’s componentId

Also while I’m at it - use fade animation when setting root

* Merge BottomTabs options

Merge BottomTabs options when calling mergeOptions with BottomTabs componentId

* Fixes options

Only text size was taken into account

Mostly leftover code related to shared element transition

When TopBar is initially hidden it’s never measured, therefor when pushing a screen we need to wait for it to be measured before taking its height into account
when handling drawBehind properties and the like.

startApp animation was renamed to setRoot and is available only on Android

This commit started with a small fix to a TopBar visibility issue detailed in #3971 which unveiled
a few issues with how options are resolved and merged.

TopBar visibility
The initial TopBar visibility issue was a result of hide animators now being cancelled when pushing another screen.
Another issue was that if the TopBar was not measured (Initial stack child was shown with `TopBar.visible = false`),
the start value passed to the Y translation was 0. This commit makes sure the TopBar show animation starts after the TopBar is measured.

Options issues
When resolving current issues in ParentControllers, the options of the current child were wrongfully taken into account.
This commit changes options resolve logic so that initial options (and options dynamically merged to them via mergeOptions call) are merged.

Pull presentation logic from Navigator to rootPresenter

This commit also resolves the setRoot animations correctly with default options and current child options

* Refactred options and added tests

* fixes tabBarItem

* tests fix

* Better namings

* Clean overlay creation

By default, gestures are captures when you layout a sideMenu, regardless of whether you disable the sideMenu. This is problematic when you want to push a screen and have the swipe back gesture pop the newly pushed screen, instead of opening the drawer.

This PR simply disabled gestures when the sideMenu is disabled, and enables when the sideMenu is enabled. It resolves #3651

* Refactor peek and pop

* Rollback some XCode stuff

* Added tests for touchablePreview event

* Also fixing searchbarcancelpressed event

* Making sure tests work

* Closes #3787

* Merge options only when viewController conforms to RNNRootViewProtocol

* better practice

* Fixes e2e

** For iOS only

When a root containing a stack with multiple children was displayed, initial stack children were
missing back button.

The actual `registerComponentWithRedux` function definition is the following:
```
    registerComponentWithRedux(componentName, getComponentClassFunc, ReduxProvider, reduxStore) {
        return this.componentRegistry.registerComponent(componentName, getComponentClassFunc, ReduxProvider, reduxStore);
    }
```

Note the order of `store` and `provider` are the opposite as shown in the original documentation.  This will fix it, but it's worth mentioning that v1 has the order shown in the original documentation, so it would be nice to keep the parameter order the same in v2.

* Added all styling options and WIP comments

* Completed screen options and layout types

* Added typings to the main entrypoint

* Added buttons too

* Optional fields

* Fixes js unit tests

mergeOptions support for commands
