refactor: native FFI for Android and Cocoa SDK

[vaind]

:scroll: Description

This is an evaluation/PoC for integration of the iOS/macOS (a.k.a. Cocoa) SDK as well as Android (Java) SDK via direct FFI invocation, avoiding method channels.

Tracking issue: #1444

Currently, this PR only ads the configuration & code generated to make the necessary change & I've tested a full call roundtrip for both SDKs.

:bulb: Motivation and Context

:green_heart: How did you test it?

:pencil: Checklist

• [ ] I reviewed submitted code
• [ ] I added tests to verify changes
• [ ] No new PII added or SDK only sends newly added PII if sendDefaultPii is enabled
• [ ] I updated the docs if needed
• [ ] All tests passing
• [ ] No breaking changes

:crystal_ball: Next steps

Decide whether we want to go ahead and implement this fully - replacing the functionality currently implemented in platform-specific method channels.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!
