BaseTools/VfrCompile/Pccts: Add virtual destructor for class DLGInputStream
Class DLGInputStream defined in DLexerBase.h has a virtual method but no
virtual destructor.
This commit add an empty virtual destructor to avoid potential
memory/resource leak when an object of a class derived from class
DLGInputStream is deleted through a pointer to the DLGInputStream class.
