Summary:
This re-applies Consider relative to pwd installation root when looking for files in rn module via cocoapods by danilobuerger
The `:reactNativePath` provided by `use_native_modules!` is the rn module path relative to the installation root (usually `./ios`). However, when executing cocoapods from a dir thats not the installation root, packages that use the relative `:reactNativePath` variable in their path must also consider the relative to pwd installation root.
This fixes usage of cocoapods with the `--project-directory` flag like
```bash
bundle exec pod install --project-directory=ios
```
## Changelog

Pull Request resolved: https://github.com/facebook/react-native/pull/33427
Test Plan:
1) Enable the new arch

```bash
bundle exec pod install --project-directory=ios
```
3) It will fail with
```
[!] Invalid `Podfile` file: [codegen] Couldn't not find react-native-codegen..
```
4) Apply the patch
5) Execute from the projects root dir
```bash
bundle exec pod install --project-directory=ios
