Checks whether the given SE_String is an "empty" string.
NOTE: Do NOT use a pointer comparison on the string value with se_empty_string; a string is empty if it is of length zero, not just if it equals se_empty_string.
| SE_DRM_STAT_CODE_SUCCESS | and *result_out_ptr is set to the appropriate value, if valid parameters were passed in. |
| SE_DRM_STAT_CODE_NULL_REQUIRED_PARAMETER | and no changes are made, if string_ptr or result_out_ptr is NULL. |
| SE_DRM_STAT_CODE_FAILURE | and *result_out_ptr is set to SE_FALSE, if string_ptr->characters is NULL. |
