Fix CPU bitwise shifts for out-of-limit shift values (#96659)
Negative shift values and positive shift values greater than the bit size of the dtype (limit `0..bits`) now yield expected results which are consistent with numpy.
Left shift with an out-of-limit shift value result in a value of `0`. Right shift with an out-of-limit shift value results in a value of `-1` for negative inputs and `0` for non-negative inputs (sign preserving).
