Add Rust representation for CHGate, CPhaseGate, CSGate, CSdgGate, CSXGate, CSwapGate

[ElePT]

Summary

This PR adds Rust representations for:

• CHGate
• CPhaseGate
• CSGate
• CSdgGate
• CSXGate
• CSwapGate

As part of #12566.

Details and comments

This PR also includes placeholders for all missing gates in #12566 with a dummy number of qubits and number of parameters (34) that should be replaced with the actual number when implemented. It's redundant with #12646, which I added in case it could help out other contributors while this PR got sorted out. If this PR gets approved before #12646 there's no need for it.
