@vjatoth-qti, would the intended use of this in a recipe look like this?
"st": {
"type": "StaticLLM",
"batch_size": 1,
"context_lengths": [1, 64]
}Do we ever expect len(context_lengths) > 2? If not, it seems like we could follow the NPU strategy for StaticLLM, where "context_length": x always implies a hybrid AR1 + ARx model, and we wouldn't need a new "context_lengths" key.

Is enable_gpu_weight_sharing a supported provider option? The corresponding PR to onnxruntime-qnn (onnxruntime/onnxruntime-qnn#67) does not add it as one.
