/**
 * Test Description
 * ------------------------
 *    - Verify that node parameters get updated correctly by creating a node with valid but
 * incorrect parameters, and then setting them to the correct values in the executable graph.
 * The executable graph is run and the results of the memset is verified.
 * hipGraphMemsetNodeGetParams is used to verify that node parameters in the graph were not updated,
 * which also constitutes a test for said API.
 * The test is repeated for all valid element sizes(1,
 * 2, 4), and several allocations of different width(height is always 1 because only 1D memset nodes
 * can be updated), both on host and device
 * Test source
