Ability to capture trees as JSON files (#1565) Summary: This adds a `captureTree` method intended to be injected in somewhere where you would like a JSON representation of a yoga tree (like in calculateLayout). Right now it is very simple and just calls on `nodeToString` to serialize a node into JSON, and then saves that into a file in the `benchmark` dir. Some buck file changes needed to be done as well as this is the first `.cpp` file in `benchmark` Differential Revision: D52972995 2024-01-24 12:30:22 -08:00			`/*`

Ability to recreate yoga trees from JSON captures Summary: In the previous diffs we serialized the in-memory representation of a node into json. This diff exposes a `generateBenchmark` method that reads from that json executes the proper public Yoga API functions to recreate the same tree. It then calls calculate layout so that we can time that in the next diff. This diff is really only focusing on the core aspects of a yoga tree like style, children, and calculating layout; there are still more things to add coming up: * Support for configs, experiments, and errata * Support for measure functions * Support for general node state that is not style (like always forming a containing block) * Actually running all of these benchmarks together * Tests Differential Revision: D52987588 2024-01-24 12:30:22 -08:00			`void generateBenchmark(std::string captureName);`
