Transitive onlyLink support

[Alex009]

If we add onlyLink = true cocoapod, but nowhere not add cinterop variant of cocoapod - we will not link with this cocoapod. and because of it in moko-crash-reporting we can't use pod("GoogleUtilities", onlyLink = true)

but for now we can use:

cocoaPods {
    pod("GoogleUtilities", onlyLink = true)
}

kotlin.targets.withType(org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget::class.java).all {
    binaries.withType(org.jetbrains.kotlin.gradle.plugin.mpp.Framework::class.java).all {
        linkerOpts("-framework", "GoogleUtilities")
    }
}

need to add linker opts in onlyLink case.
