Add placeholders for all mising standard gates in Rust

[ElePT]

Summary

This PR proposes placeholders for all missing gates in https://github.com/Qiskit/qiskit/issues/12566 with a dummy number of qubits and number of parameters (34) that should be replaced with the actual number when implemented. The idea of this proposal is to allow for a better parallelization of the work that avoids conflicts. Note that I don't particularly like this order, and I think we should reorder the lists once the implementations are completed, but I think this order is better than having to resolve conflicts every time we merge a new PR. I have also added annotations in the static vectors to increase readability.
