Jira Issue-964: Add more types for OCEntityHandlerResult

OCEntityHandlerResult includes more type that matches with
CAResponseResult_t.

This patch does not modify the return value of the exisitng code
and neither changes the enum value of the existing code.
It appends to the existing list based on the CoAP return values.
