/**
Testcase Scenarios of hipGraphHostNodeSetParams API:

Functional:
1. Creates graph, Adds HostNode, update hostNode params using hipGraphHostNodeSetParams API
   and validates the result
2. Create graph, Add Graphnodes and clones the graph. Add Hostnode to the cloned graph, update
   hostNode params using hipGraphHostNodeSetParams API and validate the result

Negative:

1) Pass pGraphNode as nullptr and verify api doesn’t crash, returns error code.
2) Pass pNodeParams as nullptr and verify api doesn’t crash, returns error code.
3) Pass hipHostNodeParams::hipHostFn_t as nullptr and verify api doesn't crash, returns error code.
4) Pass unintialized host params
