`ShadowNodeFragment` is very cheap by design because it does not own stuff it contains, so it's great. But... sometimes we need to own the stuff (e.g. to pass it on the other thread), in those cases we can use `ShadowNodeFragment::Value` now.
`ShadowNodeFragment::Value` cannot be used alone, it needs to be constructed from `ShadowNodeFragment` and then used as opaque object and then it can be converted to ``ShadowNodeFragment`.
We will need it soon.

Summary:
@public
Adds `YGStyle::ValueRepr` to make code depending on the actual type easier to write.
So far, we have treated `yoga::detail::CompactValue` as an implementation detail, and that’s what it’s supposed to stay.
React Native Fabric has one value conversion overload that depends on that type, though, and used `decltype(YGStyle{}.margin()[0])` until now.
That’s problematic for two reasons:
- we want to constrain the parameter of `operator[](...)` to enum types, making the `0` unsuitable
- we want to return the non-const overload of the operator to return a custom `Ref` type, which is not the type needed by Fabric.
Making the storage type explicit allows to write more forward-compatible code.

Having binary operators as member functions has disadvantages:
- the left hand side cannot be converted to `YGFloatOptional` implicitly (which we need for `YGStyle` refs)

Apparently, `DEBUG` is non-standard feature and using `assert` with `DEBUG` is practically asking for bugs. So, if your `assert` relies on some variable which is only defined when `DEBUG` is set, it's easy to get invalid code because NDEBUG and DEBUG can be unsync.
So, we have to use clunky double negative `#ifndef NDEBUG` everywhere where we used DEBUG.

In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.

Remove unnecessary `const` and `extern` specifiers from `Yoga.h`.
- Function declarations are `extern` by default
- The removed `const` specifiers for pass-by-valye parameters are only meaningful for the *definition* of functions, not for the declaration.
In this specific case, I found `const YGNodeRef` particularly confusing, as it is a `typedef` for a pointer type. `const` does not refer to the pointed-to object, but to the parameter itself, i.e. `const YGNodeRef` is `YGNode * const`, and not `const YGNode *`.

Summary:
If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.
