Replace java.util.Objects with io.sentry.util.Objects

[romtsn]

📜 Description

Since our minSdk is 16 (14 in fact, but nobody is using that already), we cannot use java.util.Objects because it's available only from API 19.

💡 Motivation and Context

💚 How did you test it?

📝 Checklist

• I reviewed the submitted code
• I added tests to verify the changes
