Fix binding errors using Metadata.xml transforms instead of Additions

- Revert AssemblyInfo.cs to preserve build placeholders
- Remove problematic APIs via Metadata.xml transforms:
  - androidx.heifwriter: Remove setCallback method with invalid type reference
  - com.google.crypto.tink: Remove getEnforceNamingStyle method with wrong return type
  - com.squareup.okhttp3.okhttp-tls: Remove trust manager methods with signature mismatches
