[NTOBJSHEX] Use STDMETHOD macro and keyword override (#6566)
For simplicity and short typing.
JIRA issue: CORE-19469
- Replace "virtual HRESULT 
  STDMETHODCALLTYPE m" with
  "STDMETHOD(m)" (m is a
  method name).
- Replace "virtual t
  STDMETHODCALLTYPE m"
  with "STDMETHOD_(t, m)"
  (t is a type. m is a method name).
- Use "override" keyword as possible.
