James Treanor 6ef91061e8 CocoaPods frameworks compatibility: Step 1 (#25496)
Summary:
This is the first step towards fixing https://github.com/facebook/react-native/issues/25349. These are the changes to the podspec to correctly update dependencies and build config that will cause any breaking change for users or libraries.

I am breaking these changes out from https://github.com/facebook/react-native/pull/25393 as suggested by fkgozali in https://github.com/facebook/react-native/pull/25393#issuecomment-508322884.

These are the changes:

- Made C++ headers in `React-Core` private by default so that ObjC files can import the module without failures.
- Reduced the number of `yoga` headers that are exposed for the same reason as above. As far as I can see this doesn't cause issues but we can find another solution if it does.
- Adding some missing dependencies to fix undefined symbols errors.
- Added `DoubleConversion` to `HEADER_SEARCH_PATHS` where it was missing.

## Changelog

[iOS] [Fixed] - Updated podspecs for improved compatibility with different install types.
Pull Request resolved: https://github.com/facebook/react-native/pull/25496

Test Plan:
Everything should work exactly as before. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which points at this branch to show that it is still working `Podfile` to demonstrate this is fixed.

You can see that it works with these steps:

1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout podspec-updates`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`

The sample app will build and run successfully.
