✨ New comparisons for `Zero`

[LVMVRQUXL]

📝 Description

We want to introduce experimental comparisons for the Zero type for supporting the following Kotlin types: Byte, Short, Int, Long, Float and Double. These operations should be available for all platforms.

Here's the Application Programming Interface (API) goal:

interface Zero {
    operator fun compareTo(other: Byte): Int
    operator fun compareTo(other: Short): Int
    operator fun compareTo(other: Int): Int
    operator fun compareTo(other: Long): Int
    operator fun compareTo(other: Float): Int
    operator fun compareTo(other: Double): Int
}
