evelant 58adc5e4b9 Fix build failure on iOS with pnpm and use_frameworks! (#38158)
Summary:
Fix build failure on iOS with pnpm and use_frameworks! due to cocoapods copying symlinked headers to wrong paths

When using pnpm all packages are symlinked to node_modules/.pnpm to prevent phantom dependency resolution. This causes react-native iOS build to fail because Cocoapods copies headers to incorrect destinations when they're behind symlinks. The fix resolves absolute paths to the header_mappings_dir at pod install time. With absolute paths cocoapods copies the headers correctly.

This commit also adds a few missing header search paths in use_frameworks! mode.

Fixes https://github.com/facebook/react-native/issues/38140

Pull Request resolved: https://github.com/facebook/react-native/pull/38158

Test Plan:
1. `pnpm pnpx react-native@latest init AwesomeProject`
2. `cd AwesomeProject`
3. `rm -rf node_modules yarn.lock`
4. `mkdir patches`
5. copy [react-native@0.72.1.patch](https://github.com/facebook/react-native/files/11937570/react-native%400.72.1.patch) to `patches/`
6. Add patch to package.json
```
"pnpm": {
    "patchedDependencies": {
        "react-native@0.72.1": "patches/react-native@0.72.1.patch"
    }
}
```
7. `pnpm install`
8. `cd ios`
9. `NO_FLIPPER=1 USE_FRAMEWORKS=static pod install`
10. `cd ..`
11. `pnpm react-native run-ios`

Hopefully an automated test of building with `pnpm` can be added to CI. I don't know how to make that happen, hopefully someone at facebook can do it.
