   When I implement the left/right shift operation for the bitwise, I meet a issue.
   
   In the rust, the operation` << or shl` will be overflow which don't like the ` bitand, bitor`.
   The `warpping_shl` just support `wrapping_shl(self, u32) -> Self`, the `wrapping_shl` for generic type is feature in the rust  https://github.com/rust-lang/rust/issues/90080
   Do you have any thoughts about that?
   
   
   Can we add a new trait like `ArrowNativeTypeOp` to support the `shl_wrapping(self, u32) -> Self`?
