Splits the input simd or simd_mask object into multiple simd or simd_mask objects.

1-2) split the input object into potentially different types (e.g. types with different sizes) of objects. These functions do not participate in overloading resolution unless Sizes... sum up to v.size().
3-4) split the input object into a array of objects. These functions do not participate in overloading resolution unless

- The array element must be of type simd or simd_mask, for the type of v as simd or simd_mask, respectively.
- simd_size_v<typename V::value_type, Abi> is an integral multiple of V::size().

### Parameters

v | - | the input simd or simd_mask object

### Return value

1-2) a tuple that contains the splitted simd or simd_mask objects.
3-4) an array that contains the splitted simd or simd_mask objects.
