Joshua Gross 6be37d8c0a Use a mutex to guard access to lastLayoutMetrics_ in ViewEventEmitter
Summary:
Of course, compare_exchange_strong didn't actually do what I wanted.

Using a mutex is simpler and actually has the semantics we want: atomically get the current value, compare, and bail if the value is the same, or swap and continue.

Joshua Gross 928fe129db Core: ViewEventEmitter should not emit duplicate onLayout events
Summary:
Simple hack to prevent duplicate onLayout events from being emitted to JS.

Because of the addition of State Reconciliation to the Fabric lifecycle (see previous diff), in certain circumstances entire subtrees can be relayed-out many, many times even though they aren't changing. For JS product code that responds to every onLayout and forces a ReactJS tree commit (see: some usages of VirtualizedList) this can cause an async infinite loop of commits and layouts even though the tree and the LayoutMetrics aren't actually changing. Even though nothing is changing, it can still cause serious performance regressions and even some bugs since the internals of various state machines may assume onLayout won't be called many times.

Valentin Shergin 3ad5c9e016 Fabric: Enabling clang-format for half of Fabric modules
Summary:
All code styles are terribly ugly. We have the only choise - choise something and embrace it.
This particular code style was borrowed from a neibour Fabric-friendly project because it follows established Facebook guides and respects client-side traditions.

Ramanpreet Nara 7c0b707754 Extract TouchEventEmitter from ViewEventEmitter
Summary: In the future, we may want some components (like Virtual Text) to handle only touch events. Therefore, I've extracted `TouchEventEmitter` from `ViewEventEmitter`.
