🚀 Enhancement: Auth permissions (Users API client side)

### 🔖 Enhancement description Allow setting permissions in the users API so other users can access certain things such as user name, user ID, etc client side. It will be important to make it customizable what things should be returned. ### 🎤 Pitch That way we avoid having a duplicated collection/table in the database API for getting the users name, etc. Also it will make the management easier and have more consistence. Avoiding duplicated data is fundamental in medium sized to big apps. ### 👀 Have you spent some time to check if this issue has been raised before? - [X] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [X] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
