0023912: TDataStd_ExtStringArray::Value() returns a copy of TCollection_ExtendedString, but it might return a reference.

Browse Source 
Since now TDataStd_ExtStringArray::Value() returns a constant reference to the string value.
Also, a draw-command GetExtStringArray is modified to manipulate with the string by a constant reference.
Added test case bugs/caf/bug23912
