0027067: Avoid use of virtual methods for implementation of destructors in legacy classes

Redundant methods Delete() and Desroy(), created in CDL as a hack to define destructor for the class, are removed; their definitions are converted to definition of destructors. In a couple of places methods Destroy() are preserved (bug made non-virtual) because they are called explicitly.
