Add Parcelable implementation for ApfCapabilities
This is necessary to allow usage of ApfCapabilities as-is in AIDL,
instead of relying on ApfCapabilitiesParcelable, assuming that stable
AIDL starts allowing usage of @SystemApi classes. The Parcelable
implementation would be convenient for clients in any case.
