Fixes KT-19853. The CREATOR field is a static field on a Parcelable class which is not visible from Kotlin since the necessary metadata would have to be in a Companion object which may not exist. This commit adds a [parcelableCreator] function to kotlinx.parcelize, which is optimized to a direct field access whenever possible.
