Translates a single OpenQASM gate definition into Elixir source code that defines an equivalent circuit-transforming function.

The generated function has the signature

def name(circuit, p1, p2, ..., q1, q2, ...)

— circuit first, then declared parameters in source order, then qubit arguments in source order — and returns a new circuit with the expanded gate body applied.

Only stdgate references are emitted in v1; nested user-defined gate references and modifiers (inv, pow, ctrl, negctrl) are rejected with Qx.QasmUnsupportedError upstream in the parser/lowering layer.
