Remove HostnameVerifier option

[romtsn]

📜 Description

This was mainly used by self-hosted users who has a self-signed certificate. There will be 3 options for them going forward:

• Provide a custom ITransportFactory, where they can copy over most parts like HttpConnection and AsyncHttpTransport with necessary modifications
• Get a certificate for their server through e.g. Let's Encrypt
• Fork the SDK and add the hostname verifier back

It's a breaking change, but we agreed that the impact is gonna be so small that it's not worth waiting for the next major, given that it produces so many false positives by security tools of some app stores

💡 Motivation and Context

Closes getsentry/sentry-unity#1513

💚 How did you test it?

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
