Refactor: Use an interface for dark mode detector

[amir1376]

🚀 Description

Provide a way to use the dark mode detector module in an un-opinionated way.

📄 Motivation and Context

At the moment there is no common way for non-compose or custom setups to use this module. maybe someone wants to check system dark mode in non-compose logic. or an app which has no dependency to compose at all.

🧪 How Has This Been Tested?

Unfortunately due to internet shutdown in Iran I was unable to compile the project. there are no big changes in this PR just some refactoring! so I think everything should be fine.

📦 Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

✅ Checklist

• My code follows the code style of this project.
• My change requires a change to the documentation.
• I have updated the documentation accordingly.

in order to help non-compose users can also benefit from this library as well - I suggest to separate this module into darkmode-detector-core and darkmode-detector-compose
