✨ New ZeroAsLongSerializer type

[LVMVRQUXL]

📝 Description

Similarly to #690, in the types-kotlinx-serialization subproject, we want to introduce the ZeroAsLongSerializer experimental type for serializing the Zero type as Long.

class ZeroAsLongSerializer : KSerializer<Zero> {
    override val descriptor: SerializerDescriptor

    override fun equals(other: Any?): Boolean
    override fun hashCode(): Int
    override fun serialize(encoder: Encoder, value: Zero)
    override fun deserialize(decoder: Decoder): Zero
    override fun toString(): String
}

This serializer should be available for all Kotlin platforms.
