fix: use dp for selection events

[kirillzyusko]

📜 Description

Use dp for selection events.

💡 Motivation and Context

If we pass values directly, then we will have incorrect positioning, because we are passing px while RN relies on dp. So in this PR we are converting all selection coordinates in dp and only then pass them.

📢 Changelog

Android

• convert all selection coordinates to dp;

🤔 How Has This Been Tested?

Tested manually on Pixel 3a (API 33, emulator).

📸 Screenshots (if appropriate):

Pay an attention to x coordinates 👀

📝 Checklist

• CI successfully passed
• I added new mocks and corresponding unit-tests if library API was changed
