4b248f20 - [flang][cuda] Widen stream argument to i64 in stream intrinsic lowering (#196650)

[flang][cuda] Widen stream argument to i64 in stream intrinsic lowering (#196650) `genCUDASetDefaultStream` and `genCUDAStreamDestroy` build their runtime call with an `i64` stream parameter but pass the actual argument straight through, so a smaller-kind actual (e.g. the literal `0` in `cudaforSetDefaultStream(0)`) produces an ill-typed `fir.call`: ``` error: 'llvm.call' op operand type mismatch for operand 0: 'i32' != 'i64' ``` Insert a `fir.convert` to `i64` before the call, matching what `genCUDASetDefaultStreamArray` already does.
