Fix `Scalar::is_zero` for `FixedSizeList` and `Struct` `Scalar::is_zero` previously only checked the element/field count for `FixedSizeList` and `Struct` values, so any non-null struct or fixed-size list was reported as zero. Recurse into the elements/fields and require every one to be a non-null zero value, matching the documented `Scalar::zero_value` semantics. Add regression tests covering non-zero elements/fields, null elements/fields, and a nested struct-of-fixed-size-list value. These fail against the previous element-count-only behavior.

Generalize SIMD `take` operations to `Copy` (#8496) ## Summary Closes: https://github.com/vortex-data/vortex/issues/5677 Changes the `NativePType` bound to `Copy`, which allows us to deduplicate a bunch of code. Imo this is also easier to read. ## Testing Existing tests should suffice --------- Signed-off-by: Connor Tsui <connor.tsui20@gmail.com>
