Support bit_not for Bool type

[hhorii]

Summary

This PR is to support bit_not for Bool values.

Details and comments

bit_not is defined for Uint values. However, in other language, depending hardware, Bool values can be applied as logical_not (False is 0 and True is 1). This PR supports such implicit operations for only "bit_not".

Ed Chen pointed out to me that bit_xor (and I would guess bit_or) has the same problem - not supported on Terra's pseudo Bool/bit type in Aer. Can we make bit_xor, bit_or and bit_and work on bit/bools as well?

@jakelishman Thank you for your comments.
I have added a test case to check bit_xor works Bool ^ Bool -> Bool and Uint ^ Uint -> Uint cases (I believe that Bool ^ Uint is not allowed in Qiskit). I think current implementation covers these operation. Could you tell what cases Ed Chen wants?
