Mostly relevant to malformed icons where for some reason, requiring an image results in null.

* WIP

* Revert "Layout changes"

This reverts commit 4da8cfbd12.

* Move custom components login from viewController to presenters

* Change waitForRender and enabled property from primitive bool to Bool object

* Fix ios unit tests

* Add unit tests

* Remove RNNReactView observer when view ready

* Load react components from component manager

* Remove createCustomReactView duplication

* Handle render children in each Layout

* Wait for navigation presenter components render, refactor RNNTitleViewHelper

* Fix unit tests

* Add waitForRender for custom react components

* Fixes e2e

Event was emitted with parent id instead of the id provided by the user, which could be an id on one of the modals children.

fixes #4693

Seems like RNNSplitViewOptions wasn't updated to use the presenters, so
the options were going nowhere.

* fixes noBorder issue with largeTitle

* fixes issue that change navigationbar title color to default

the generic buttonColor doesn't work for android. Backbutton color is not documented, see #3454

Id property wasn’t handled when copying back button in native

Add Modal Dismissed Event Listener to doc

The bottomTab settings were not being properly applied if a SplitView
controller was nested. Part of this seems to be that the 'options' for
SplitView were in their V1 form, i.e. they did not have access to the
full topBar/bottomTab/etc.

I refactored the options to be in their own subsettings. NOTE: the
settings for splitView are not being applied currently -- they weren't
before and they still are not now.

With access to the full options now, I was able to change
RNNSplitViewController to properly override
willMoveToParentViewController to get the bottomTab icon to properly
show up.

This pr adds support for changing tab initialisation mode. Currently bottom tabs are attached together and consequently, their corresponding react root views are created and rendered. This adds lots of stress on the js thread and hiders app start time.

To mitigate this issue, this pr adds support for three modes
* `together` (default, current behaviour) - all tabs are loaded together, adding unnecessary load on the js thread as we're loading invisible views, which leads to increased app start time.
* `afterInitialTab` - Initial tab is loaded first. After it is rendered, other tabs are loaded as well. This should shave a few hunderdish ms from app start time. Since other tabs are loaded after the initial tab is visible, the ui might be unresponsive for a few hunderdish ms as multiple root views (which are typically complex) are being created and attached to hierarchy at once.
* `onSwitchToTab` - initial tab is loaded. Other tabs are loaded when switching to them (tab click or programmatically). While this won't stress js thread after initial tab is rendered, there will be a flicker when entering a tab for the first time as it's ui isn't ready.

* Add color to tintColor

Seems like CI env variable is obsolete

RNN supports static options provided as both functions and objects.

Add missing type interface "waitForRender"

This fixes a bug which occurred when returning from background - sometimes the system would set
an unexpected elevation value which seems like the default elevation.
This commit checks if the new elevation value was specified by RNN before setting it.

This reverts commit 05dacbd072.

Fixes an issue with ScrollView inside an Overlay. While down events were propagated to the view, move events were consumed by the overlay preventing scroll components from functioning correctly.
