We're moving `CompactValue` to be an internal detail of `yoga::Style`, where users outside of the style will be dealing with a resolved/non-compact representation.
This change renames usages of `CompactValue` to `Style::Length`, which will be Yoga's representation for CSS input lengths. Right now one is just a type alias of the other, but this will let us change the internals of CompactValue with the rest of the world looking the same.
A few factory functions are added to `yoga::value` for creating CSS values. There are some shenanigans around how we want to represent CSS pixels (one YGUnitPoint), when we also end up adding CSS points (slightly larger than one YGUnitPoint). For now, I reused `point` until making other changes.

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 diff
This diff adds a `style` directory for code related to storing and manipulating styles. `YGStyle`, which is not a public API, is renamed to `yoga::Style` and moved into this folder, alongside `CompactValue`. We will eventually add `ValuePool` alongside this for the next generation style representation.
## This stack
The organization of the C++ internals of Yoga are in need of attention.
1. Some of the C++ internals are namespaced, but others not.
2. Some of the namespaces include `detail`, but are meant to be used outside of the translation unit (FB Clang Tidy rules warn on any usage of these)
2. Most of the files are in a flat hierarchy, except for event tracing in its own folder
3. Some files and functions begin with YG, others don’t
4. Some functions are uppercase, others are not
5. Almost all of the interesting logic is in Yoga.cpp, and the file is too large to reason about
6. There are multiple grab bag files where folks put random functions they need in (Utils, BitUtils, Yoga-Internal.h)
7. There is no clear indication from file structure or type naming what is private vs not
8. Handles like `YGNodeRef` and `YGConfigRef` can be used to access internals just by importing headers
This stack does some much needed spring cleaning:
1. All non-public headers and C++ implementation details are in separate folders from the root level `yoga`. This will give us room to split up logic and add more files without too large a flat hierarchy
3. All private C++ internals are under the `facebook::yoga` namespace. Details namespaces are only ever used within the same header, as they are intended
4. Utils files are split
5. Most C++ internals drop the YG prefix
6. Most C++ internal function names are all lower camel case
7. We start to split up Yoga.cpp
8. Every header beginning with YG or at the top-level directory is public and C only, with the exception of Yoga-Internal.h which has non-public functions for bindings
9. It is not possible to use private APIs without static casting handles to internal classes
This will give us more leeway to continue splitting monolithic files, and consistent guidelines for style in new files as well.
These changes should not be breaking to any project using only public Yoga headers. This includes every usage of Yoga in fbsource except for RN Fabric which is currently tied to internals. This refactor should make that boundary clearer.

Summary:
`/*` 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.

Summary:
After this diff D13403925 that got rid of `-ffast-math` we started to have a very odd behavior on Yoga when using release builds.
After digging a while we found that certain set of conditions on O2 and O3 optimization levels was causing Origami to set some `INFINITE` values on Yoga.
We found the root of the problem and fix it on Origami side. But I'm wondering if guarding agains `INFINITE` on Yoga side would be good too. Since now Yoga it's not using `-ffast-math` anymore, and I think infinite is not a a valid value anywhere on Yoga side, it seems to support the reason to guard against it.
I'm happy to abandon this diff if you guys think this is not a good solution.

Summary:
@public
`CompactValue` represents a `YGValue` in 32bits instead of 64. This comes at the cost of a range limitation, as one exponent bit is borrowed for the unit.
*Undefined* and *Auto* have no magnitude, and are represented as *NaN* values.
The data structure is meant to be used as a field type on `YGStyle` to save memory.
This is header-only for efficient inlining.
