Parcelize: Use @Parcelize annotations from Android Extensions instead of the copied&deprecated ones (KT-42342, KT-43150)

Dex can't merge class files from both android-extensions-runtime and parcelize-runtime, so we have to keep only one copy of each class.
Instead of @Deprecated annotations, there are new diagnostics (without quick-fixes yet).
The goal is to allow simple usages (@Parcelize alone) but forbid kotlinx.android.synthetic.Parceler usage.
