0029258: Foundation Classes - provide move constructors for string classes

Browse Source 
New macro OCCT_NO_RVALUE_REFERENCE is introduced to disable methods using move semantics on obsolete compilers that do not support rvalue references.

TCollection_AsciiString, TCollection_ExtendedString, NCollection_UtfString - added method Swap(), move constructor, and move assignment operator.

Draw command QATestArrayMove is added to test for memory corruption if NCollection_Array1<> bound to local C buffer is returned from function by value.
