Enhance interceptor code in rayaop.c

This update significantly expands the interceptor code within the src/rayaop.c file. The changes provide functionality for handling NULL objects and setting parameters for the intercept handler. If the intercept handler's function call is successful, the return value is copied. If it's unsuccessful, an error message is generated. Some code cleanup steps have been also added after completing these operations.
