Summary:
Previously <TextInput>'s onContentSizeChange event fires very rearly, usually just once after initial layout. This diff fixed that.
I also considered to a bunch of another things to get the native notification, but I found that overriding `onTextChanged` is the most reliable, easy and effitient way to implement this.
I tried/considered:
* onLayout (does not fire)
* OnPreDrawListener (fires to often)
* OnGlobalLayoutListener (does not fire)
* OnLayoutChangeListener (does not fire)
* isLayoutRequested (too hacky)
(I also fixed the <AutoExpandingTextInput> demo to illustrate the fix.)
And just heads up, we will remove `contentSize` info from `onChange` event very soon.

Summary:
Fixes https://github.com/facebook/react-native/issues/13784
The section footer was only rendered with the last item of the section. However, that meant in sections where no items were rendered, no section footer would be rendered. This patch makes sure that when there are no items the section footer is rendered with the section header in addition to adding tests asserting the existance of section footers in empty lists.
One potential point of contention is whether or not a section separator (as defined by the `SectionSeparatorComponent` prop to `<SectionList>`) should be rendered in an empty list. I did not include a section separator for empty lists, but let me know if you think one should be included. See the test plan below for an image of an empty section rendered without a section separator.
I was also running into a lint error, `no-alert`, in `SectionListExample.js` around line 135 that blocked me from publishing. This error looks to be triggered when the `alert()` global function is called, so to fix the error I added an import for the `Alert` module and called the `alert()` function on that module.
To help debug the `scrollToLocation()` behavior that was modified as a part of this PR I added three buttons (can be seen in the test plan image) which scroll to arbitrary points in the list.

Summary:
**Motivation**
The ART library is part of the react-native repo, but is not included in UIExplorer and has no native testing. This PR adds the ART library to UIExplorer, adds an example tab for it, and adds a snapshot test.
**Test plan**
New snapshot test.

Summary:
We are removing support of nesting views inside <Image> component. We decided to do this because having this feature makes supporting `intrinsinc content size` of the `<Image>` impossible; so when the transition process is complete, there will be no need to specify image size explicitly, it can be inferred from actual image bitmap.
And this is the step #0.
<ImageBackground> is very simple drop-in replacement which implements this functionality via very simple styling.
Please, use <ImageBackground> instead of <Image> if you want to put something inside.
