Valentin Shergin fc0b03a0d1 Fabric: Small perfromance optimization in [RCTViewComponentView updateLayoutMetrics:oldLayoutMetrics:] ...

Summary:
Before this change, we reapply all layout props for all newly mounted views (on `insert` instruction), now we use stored `_layoutMetrics` value to apply only changed subset.
This is only available for `RCTViewComponentView` subclasses (where we have an ability to store a previous value), all other implementation of `RCTComponentViewProtocol` will work as usual.
