BaseTools: Make AutoGen.h array declaration match AutoGen.c definition 

When a quoted string is used as initialization data in a DEC file PCD
entry, the PCD data type in that entry must be VOID*. The created
AutoGen.c defines the PCD data as UINT8[] or UINT16[], depending on
the string type. The created AutoGen.h, however, declares the PCD data
as VOID*. For a standard compile/link, this works because AutoGen.c
doesn't include AutoGen.h. But when GCC LTO is used, the link time
code generation detects the mismatch and the build fails. This
change makes the AutoGen.h PCD data declaration match the AutoGen.c
definition.
