Mengdi Chen c54e3541b2 [DevTools] bug fix for Hydrating fibers (#25663)

hydrating Server Components

To reproduce:
1. setting up a vercel next.js 13 playground locally
https://github.com/vercel/app-playground
2. visit http://localhost:3000/loading
3. click "electronics" button to navigate to
http://localhost:3000/loading/electronics to trigger hydrating
4. inspect one of the skeleton card UI from React DevTools extension

### The root cause & fix
This bug was introduced in #22527. When syncing reconciler changes, the
value of `Hydrating` was copied from another variable `Visibility` (one
more zero in the binary number).
To avoid this kind of issue in the future, a new file `ReactFiberFlags`
is created following the same format of the one in reconciler, so that
it's easier to sync the number without making mistakes.
The reconciler fiber flag file is also updated to reflect which of the
flags are used in devtools

## How did you test this change?

I build it locally and the bug no longer exist on
http://localhost:3000/loading
