Describe the feature

Braket allows enabling Debias error mitigation when submitting tasks to IonQ. For details, and an example of how this is done in the Braket Python SDK, see here: https://docs.aws.amazon.com/braket/latest/developerguide/error-mitigation-ionq.html#error-mitigation-ionq-debiasing

The CUDA-Q code which constructs the CreateQuantumTask request to Braket begins here:
https://github.com/NVIDIA/cuda-quantum/blob/43c635ea6a06712cb47c153c8b4e4a4b89125782/runtime/cudaq/platform/default/rest/helpers/braket/BraketExecutor.cpp#L200-L203

That code does not currently include any logic to set deviceParameters in the request (see API reference here).

The feature request here is to plumb through an option to allow the user to specify general deviceParameters when submitting tasks to Braket, so that Debias error mitigation (and any other features that can be enabled via deviceParameters) can be enabled for these tasks.

Start in runtime/cudaq/platform/default/rest/helpers/braket/BraketExecutor.cpp around the CreateQuantumTask request construction, then review the AWS CreateQuantumTask API and the linked Braket Python SDK example. Trace how task submission options reach this request and define completion as allowing user-specified deviceParameters, including IonQ Debias configuration, to be submitted.
