SentryObjC dynamic framework artifacts ship no dSYMs

• Sentry-Dynamic.xcframework: ships dSYMs/ per slice
• SentryObjC-Dynamic.xcframework: no dSYM bundles at all, and the binaries are unstripped

Verified in 9.16.1 and 9.17.0 releases.

Proposed solution: Run the same dSYM step as Sentry-Dynamic.

I'm integrating SentryObjC in the Sentry's Godot SDK where this issue surfaced:
