chore: improve codegen error when native project not found (#53726)

Browse Source 
Summary:
While working on a somewhat non-standard library setup I ran into:

`[Codegen] TypeError [ERR_INVALID_ARG_TYPE]: The "from" argument must be of type string. Received undefined`

which was caused by `xcodeproj` file not found. The issue was on the project side rather than codegen, but the error message was rather unhelpful, so this improves it.

## Changelog:

[General][Changed] - improve codegen error when ios native project not found

Pull Request resolved: https://github.com/facebook/react-native/pull/53726

Test Plan:
tested locally, received the improved error message:

`[Codegen] Error: Cannot find .xcodeproj file inside /Users/some_project. This is required to determine codegen spec paths relative to native project.`
