fix(objc): Keep SentryCppHelper in initial targets array

SentryCppHelper must remain in the initial targets array because the
binary distribution products (Sentry, SentrySwiftUI, etc.) depend on it.

Moving it to the compile-from-source section broke those binary products.
The target can be safely referenced by both binary and source products.
