commit 929edd7c1e458d3f6ba5dc032f9d9d2dbd271ccb

MAHOUT-828 Add unit tests for single-qubit gates and swap test
functionality (#837)
* Add unit tests for single-qubit gates and swap test functionality
- Implemented comprehensive tests for Pauli X, Y, Z, Hadamard, NOT, U, and
T gates, ensuring correct state transitions and probabilities across different
backends.
- Added edge case tests for single-qubit gates, including handling
uninitialized circuits and invalid qubit indices.
- Introduced a swap test class to validate the behavior of swap tests with
identical, orthogonal, and identical one states, including consistency checks
across backends.
- Verified the existence and functionality of the CSWAP gate.
* Skip QDP tests if dependencies are not available in pytest configuration
