Enum VariantToArrowRowBuilder 

pub(crate) enum VariantToArrowRowBuilder<'a> {
    Primitive(PrimitiveVariantToArrowRowBuilder<'a>),
    BinaryVariant(VariantToBinaryVariantArrowRowBuilder),
    WithPath(VariantPathRowBuilder<'a>),
}

Builder for converting variant values into strongly typed Arrow arrays.

Useful for variant_get kernels that need to extract specific paths from variant values, possibly with casting of leaf values to specific types.
