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

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.

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

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.
