/**
 * Merges all properties from CVA functions.
 * If there are multiple properties with the same name and different possible values, the union of the value will be a product set.
 *
 * 1. Apply `VariantProps` to all union items to get props
 * 2. Convert union to intersect
 * 3. Apply `NonNullableProps` to eliminate nulls
 *
 * @example
 * ```
 * type NotificationVariantProps = MergeVariantProps<
 *   | typeof notificationContentClassName
 *   | typeof notificationIconClassName
 *   | typeof notificationIconContainerClassName
 *   | typeof notificationContainerClassName
 * >;
 * ```
