unaryMinus operation for AnyInt hierarchy

[LVMVRQUXL]

💡 The idea

We would like to implement the following unaryMinus operations for the AnyInt hierarchy:

/** Returns the negative of this integer. */
operator fun AnyInt.unaryMinus(): Int
operator fun NonZeroInt.unaryMinus(): NonZeroInt
operator fun PositiveInt.unaryMinus(): NegativeInt
operator fun NegativeInt.unaryMinus(): PositiveInt
operator fun StrictlyPositiveInt.unaryMinus(): StrictlyNegativeInt
operator fun StrictlyNegativeInt.unaryMinus(): StrictlyPositiveInt
