/**
Testcase Scenarios of hipGraphMemcpyNodeSetParamsToSymbol API:
Functional :
1) Allocate global symbol memory, add the node to the graph.
 Set/Update the new values to the node. Make sure they are taking effect.
2) Allocate const symbol memory, add the node to the graph.
 Set/Update the new values to the node. Make sure they are taking effect.
Negative :
1) Pass GraphNode as nullptr and check if api returns error.
2) Pass symbol ptr as nullptr, api expected to return error code.
3) Pass src ptr as nullptr, api expected to return error code.
4) Pass count as zero, api expected to return error code.
5) Pass count more than allocated size for source and destination ptr, api should return error code.
6) Pass offset+count greater than allocated size, api expected to return error code.
7) Pass same pointer as source ptr and symbol ptr, api expected to return error code.
8) Pass both destination ptr and source ptr as 2 different symbol ptr, api expected to return error
code. 9) Copy from host ptr to device ptr but pass kind as different, api expected to return error
code.
