Use the explicit string 'void' to refer to void in summaries.

Use the explicit string 'void' to refer to void in summaries.

Previously we used a null EntityRef as a special case to mean "void".
This saved a tiny amount of space in the summary file, but it's not
worth it because (a) it will complicate some error handling scenarios,
and (b) it would be more worthwhile to use a null EntityRef to
represent implicit types.  Both (a) and (b) will be addressed in
future CLs.

This CL changes "void" so that it's serialized as though it were
defined in the defining compilation unit of each library.
