Summary: `pullTransaction` can return an empty transaction. That's fine to interate over the empty collection and do nothing, but it's inneficient because we also call delegate methods around the loop (that can be expensive).

Summary:
In some cases, the view class is the only that retains stored `props_` variable. At the same time the `[super updateProps:props oldProps:oldProps];` actually resets the pointer with a pointer to new props value which sometimes causes the deallocation of the old value. All that is okay unless the implementation of `updateProps:oldProps:` in superclasses stores a raw reference to an old value in the very beginning of the method (for convenience and perf reasons).
So, to prevent preliminary deallocation of the old value pointed by `_props` we moved all `[super updateProps:props oldProps:oldProps];` calls to the end of overloaded methods.

Summary:
This diff contains two changes:
* The actual UIScrollView is now mounted inside the component as `contentView` which mostly means that border-props will properly affect the layout of the scroll view (the scroll view will be laid out inside borders, not on top of those). And that also simplifies the code.
* Now the component view exposes the actual scroll view, its delegate splitter, and the container view defining a single interface for all possible integration that can be done with the Scroll View Component.

Summary:
There was a reason why it exists: on iOS if you want to implement a view with rounded corners with a non-transparent background you need to set `clipToBounds = YES` to enabling clipping because besides drawing borders we need to clip the background otherwise it will "stick out".
There were a bunch of problems with this implementation and approach:
* It's overshooting. It applies `clipToBounds` no matter which border-radius is and no matter is there a background or not. So, it's kinda heuristic implementation and it's totally unexpected behavior sometimes.
* The previous problems can lead to performance problems as well (clipping requires additional work to do for CoreGraphics/GPU).
* The border-radius that we assigned to contentView is incorrect because it does not take border-width into account.
* This functionality only applies to non-null `contentView` which is a rear and custom case in which that can always be done manually for components that require that for some reason.

This is the final piece of change that makes measuring (`LayoutableShadowNode::getRelativeLayoutMetrics()`) take ScrollView content offset into account (on iOS).
It works pretty simply: at the end of scrolling (or zooming) action ScrollView updates the state which later can be used for computing `transform` which measuring uses to adjust values in LaoutMetrics.

Summary:
@public
In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.
