Continuation of #6213.
Implements some functions in const #4507.

Description
Existing macros work for component-wise cases where return type is equal to input type. But it's hard to generalize macros further. So I present LiteralVector:

/// Vector for each [`Literal`] type
///
/// This type ensures that all elements have same type
enum LiteralVector {
    F64(ArrayVec<f64, { crate::VectorSize::MAX }>),
    F32(ArrayVec<f32, { crate::VectorSize::MAX }>),
    U32(ArrayVec<u32, { crate::VectorSize::MAX }>),
    I32(ArrayVec<i32, { crate::VectorSize::MAX }>),
    U64(ArrayVec<u64, { crate::VectorSize::MAX }>),
    I64(ArrayVec<i64, { crate::VectorSize::MAX }>),
    Bool(ArrayVec<bool, { crate::VectorSize::MAX }>),
    AbstractInt(ArrayVec<i64, { crate::VectorSize::MAX }>),
    AbstractFloat(ArrayVec<f64, { crate::VectorSize::MAX }>),
}

that abstracts away at least vector obtaining logic. This makes it easier to implement some builtins that needs access to all components like dot, length, distance (folds LiteralVector to Literal) and normalize (maps LiteralVector).
