Summary: Right now invalidate always tell the root node that the tree is dirty, and next update will traverse the entire tree in search of changes. While this works correctly, it's not the most efficient implementation. It is more efficient to store dirty flag in every node, and skip entire subtrees if this node and all descendants are already up to date. This diff is a first step towards that optimization.

Summary: RootFlatShadowNode always mounts to a (top-level) View but was never marked as one that mounts to a View. This diff fixes it. Nothing in the code relied on it being marked as mounting to a View, so it worked fine. A follow up path that implements UIImplementation.measure() for nodes that don't mount to a View goes up until it finds first mounting node, and it was crashing with NPE because it tried to access RootFlatShadowNode's parent (and there isn't one).

Summary: @public Initial version of FlatUIImplementation lacks any primitives support (such as RCTText, RCTImageView or RCTView). This diff add the first part, RCTText (alongside with RCTVirtualText and RCTRawText).
