dev: Bitwise operations are not implemented natively in the corelib signed integers

[MahmoudMohajer]

Basically we have support of bitwise operations for unsigned integers in cairo by default, like bitwise and, bitwise xor, and bitwise or. In order to make them work on signed integers, we need to implement them by ourselves in the Orion library.

@MahmoudMohajer I would like to give it a try, can you please assign it to me ?
