Testcase Scenarios of hipGraphExecMemcpyNodeSetParamsFromSymbol API:
Functional
1) Allocate global symbol memory, Instantiate a graph with memcpy node,
  obtain executable graph and update the node params with set exec api call.
  Make sure they are taking effect.
2) Allocate const symbol memory, Instantiate a graph with memcpy node,
  obtain executable graph and update the node params with set exec api call.
  Make sure they are taking effect.
Negative
1) Pass hGraphExec as nullptr and check if api returns error.
2) Pass GraphNode as nullptr and check if api returns error.
3) Pass destination ptr as nullptr, api expected to return error code.
4) Pass symbol ptr as nullptr, api expected to return error code.
5) Pass count as zero, api expected to return error code.
6) Pass offset+count greater than allocated size, api expected to return error code.
7) Pass same symbol pointer as source ptr and destination ptr, api expected to return error code.
8) Pass Pass both dstn ptr and source ptr as 2 different symbol ptr, api expected to return error
code. 9) Copy from device ptr to host ptr but pass kind as different, api expected to return error
code. 10) Check with other graph node but pass same graphExec, api expected to return error code.
