Summary:
To sanity check that a capture is working as expected when running benchmark
We could maybe even throw here as a bad measure function will throw off the rest of the benchmark.

Summary: You need to provide the benchmark binary with a path to the captures. This is annoying and there is not a great way to do this in c++ that is cross-plat. So I just made this bash script to ease it. It can do buck and cmake.

Summary:
In addition to all the state that gets set on the node that is easy to serialize - like floats, enums, bools, etc - we also need to serialize measure functions. This is because these functions take a nontrivial amount of time up during layout and we should capture that. Also, they are important to the ability to truly replay layout as it was captured as the results of the measure functions determine many of the steps the layout algorithm takes.
Capturing this is rather tricky however, but I think I found a solution that is relatively simple and non-error prone. Essentially, since we are capturing the entire tree and virtually every input that goes into the flexbox algorithm, we *should* be able to replay layout exactly as it was captured. This means that the order in which measure functions are called *should* be the same. If this is the case, then all we need to do to capture the measure functions is store their input, output, and duration in a big array. During deserialization we just keep track of an index and use that to determine which measure function we should call. That is the premise behind what happens in this diff. In theory the algorithm could change and the capture would be wrong but it is easy enough to recapture again. Additionally we need to dirty the tree so that we get rid of caching which might omit some measure func calls
In order to capture you need to insert a method exposed by CaptureTree.h into the client measure func, which is kind of annoying but not that bad. In future diffs I will put a macro in place to make this even easier.
I also add our first capture! Which is of a large react native desktop app

Pull Request resolved: https://github.com/facebook/yoga/pull/1575
If we want to replay layouts for benchmark, we should also capture the inputs. This diff does that as well as changing the API in CaptureTree.h. We now expose YGCalculateLayoutWithCapture designed to be a drop-in replacement for YGCalculateLayout. This allows us to have a bit more control on the order of everything and lets us capture measure functions in the next diff much easier.

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1566
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

Summary:
This mirrors the clang-format config used by fbsource to Yoga.
They are pretty similar, except for an annoying habit where Yoga's previous forced small functions in headers to be a a single line, so you would get a combination of multiline and single line functions next to each other which are hard to read. That is what motivated this change.
It also enforces header ordering (yay). I don't think we have any side-effect causing headers, so this should be safe.

This fixes const-correctness of callbacks (e.g. not letting a logger function modify nodes during layout). This helps us to continue to fix const-correctness issues inside of Yoga.
This change is breaking to the public API, since it requires a change in signature passed to Yoga.

This enables clang warnings around potentially unsafe conversions, such as those with mismatched signedness, or ones which may lead to truncation.
This should catch issues in local development which create errors for MSVC (e.g. Dash), who's default `/W3` includes warnings akin to `-Wshorten-64-to-32`.
This full set of warnings here is a tad spammy, but probably more useful than not.

Fixes https://github.com/facebook/yoga/issues/1283
New versions of CMake add "policies" which control how the build system acts wrt breaking changes. By default, CMake will emulate the behavior of the version specified in `cmake_minimum_required`.
Setting a policy to true (to opt into new behavior where `cmake_minimum_required` is lower than the current version) seems actually just error out on the old versions.
Googling around, apparently the way I should be doing this is to specify `<policy_max>` as part of `cmake_minimum_required `. https://gitlab.kitware.com/cmake/cmake/-/issues/20392
This should I think use new policies introduced up to 3.26 (what we test on right now), while letting 3.13 be the minimum.

`/*` is the standard throughout open source code. For example, Firefox uses single /*: https://hg.mozilla.org/mozilla-central/file/21d22b2f541258d3d1cf96c7ba5ad73e96e616b5/gfx/ipc/CompositorWidgetVsyncObserver.cpp#l3
In addition, Rust considers `/**` to be a doc comment (similar to Javadoc) and having such a comment at the beginning of the file causes `rustc` to barf.
Note that some JavaScript tooling requires `/**`. This is OK since JavaScript files were not covered by the linter in the first place, but it would be good to have that tooling fixed too.
