Implement proper slice assignment for QByteArray

Index assignment now only accept str/bytes, bytearray, QByteArray with
size 1;
Slice assignment only accept str/bytes, bytearray, QByteArray with
limitation, that is if the step is not 1, then the number slots and
the size of the target value must be equal.

Range delete: a[2:5] = None
Shrink: value length smaller than the slot length of the slice
Expanse: value length bigger than the slot length of the slice
Range assignment with step: a[2:5:1] = ...
Range assignment with step which bigger than 1: a[2:9:2] = ...
Range assignment with native step: a[5:2:-1]
