21290b569b Fabric: Enable all Fabric tests for Android
Summary: All our C++ Fabric tests are cross-platform, so it makes sense to run them for all platforms (especially because platform may behaive differently).

fd3b8f2000 Fabric: Introducing Better: For faster, clear and ideomatic codebase
Summary:
`Better` is a trivial collection of basic tools borrowed from other low-level general purpose libraries (like Folly, Abseil or Boost). The main goals of Better:
 - Make the codebase more portable;
 - Make the dependency list explicit (by decoupling it as a dependency list of Better);
 - Make relying on modern C++ patterns and tools in code simple and easy.
 - Make executing experiments with different dependencies easier.

 As a first example usage, this diff replaces std::unordered_map with an efficient one from folly on the one of the hottest paths.

a9049442f7 Fabric: Use LRU to cache results of ParagraphShadowNode::measure
Summary: Use a folly LRU implementation to cache results of ParagraphShadowNode::measure, which Yoga asks for repeatedly. Should have a substantial speed improvement on Android and iOS, or at least that's the dream.

62173a1569 Introducing fabric/mounting module
Summary:
ShadowView, ShadowViewMutation, and Differentiator were decoupled to separate module.
That enables us to use ShadowView more widely without facing a circular dependency problem.
