Adding in checks for program and shader names to return INVALID_OPERATION When a valid program is given instead of a shader, an INVALID_OPERATION is returned rather than INVALID_VALUE when a shader related function is called. The reverse happens when a program related function is called and a valid shader program is given to it. This commit also refactors other places that requires a similar check to use the same validation function and error message.
