Summary:
We need to break up the `uimanager` module in order to solve circular dependencies problem (which future diff would have otherwise).

Summary:
Before this change the Element<> API didn't allow to specify state objects and crashed during instantiation of non-null states.

Summary:
Systraces were disabled a year ago in D14019272 because we suspected they can negatively affect perf. We don't think this is the case anymore.

Summary:
This is a quite fragile and important part of the render engine. We need to dirty Yoga node only in cases where a change affects layout. In the case of over-dirtying, we can kill performance. In the case of under-dirtying, we can produce an incorrect layout.

Summary:
It makes perfect sense because `Builder` builds totally new shadow trees, so those are not sealed or used by anyone yet.
Assigning it to const shared pointer will do logical sealing (and it does not requires const-cast).
Fewer const-casts in the code, fewer bugs.

Before this change `Element<X>` cannot have children of `Element<Y>` which was wrong because we don't have such limitation in Fabric.

Summary:
Changelog: [internal]
1. Creates `ShadowNodeFamily` inside `ComponentDescriptor`.
2. As a side effect of this, we no longer need `ComponentDescriptor::createEventEmitter` so it is removed.
This is a step in order to merge `StateCoordinator` into `ShadowNodeFamily` and use it as target for state updates.

Summary:
This is a part of migration staterted in D19390813.
There is no need to have those as `const`. The whole `*Props` object is usually `const` (and when it's not, props should not be too).

Summary:
`Element` is an abstraction layer that allows describing component hierarchy in a declarative way. Creating `Element`s themself does not create a component tree (aka `ShadowNode` tree) but describes some hierarchical structure that might be used to build an actual component tree (similar to XML Elements).
`Element<>` provides some basic type-safety guarantees: all modifications of element objects require using objects (such as Props or State) of compatible type.
For now, the only useful application of that is building tests.
