Refactor bottomTabs options applying mechanism. Both bottomTab and bottomTabs presenters were part of the base UIViewController class which was wrong. This commits moves them to the BottomTabsController.

This refactor mostly contains the following

* Detach bottomTabPresenter from basePresenter
* Create tabBarItem appearance on presenter init
* Refactor bottomTabPresenter
* Refactor bottomTabPresenter
* Move appearance creation to bottomTabsController
* Merge child options with direct child controller

This commit changes how stack child options are applied on iOS 13. Until now, options were applied directly to the navigationItem of the stack which is shared between all children.
This commit applies options on the navigationItem of each child instead. This fixes issues with color transitions when popping and pushing children to the stack.

Fix TopBar title animation. This commit changes how RNN handles title and subtitle.
Until now, RNN created a custom view for title and subtitle which interfered with the way the system animated the TopBar title.
With this commit the custom view is created only when both subtitle and title are declared, otherwise RNN uses the system behavior.

Send componentType field in componentDidAppear and componentDidDisappear events.

The new field is either:
- TopBarButton
- TopBarTitle
- TopBarBackground
- Component

* Remove main window backgroundColor
* Better interface for TopBarPresenter

When mergeOptions was called without a title component, existing component was undesirably removed.
This commit changes how component is removed when mergeOptions is called. It will now be removed if a component is not defined and title is defined in mergeOptions.
Fixes #5628

Break all the PRs :(

iOS and Android code base used different naming conventions - this commit aims to unify naming conventions. I probably missed a few properties here and there so this will be an ongoing effort.

* Enabled option was wrongly consumed after it was merged. That meant that the next time SideMenu options were applied, the wrong enabled value was applied
* supportedInterfaceOrientations didn't take default orientation value into account
* mergeOptions didn't save the new options in the ViewControllers current options
* SideMenu always returned the centre ViewController as the current child and didn't take open SideMenu into account

Fixes #5444

Merging TopBar title, buttons and status bar options is broken on iOS in 3.1.1.
Parent options aren't resolved properly and default options aren't regarded when they should be.

When defaultOptions are set after setRoot has been called presenters need to receive the default options as well,
otherwise the outdated default options are regarded.
Fixes #5395

This commit adds initial support for passing null as a valid value for color properties.
When a color property is applied, if it wasn't specified then the default color is applied. Now, when null is passed, no color will be applied
leaving the last color applied as is.

This is useful when showing an Overlay and you'd like to keep the current StatusBar color unaffected. Another usecase would be when you'd like to avoid coloring an icon in BottomTabs.

Add support for dot indicator to BottomTabs.
