Make SummaryBuilder's "strong" argument optional.

This will allow clients to stop passing in this argument now, so that
we can remove the argument as a breaking change in analyzer version

(Note that the argument has already been made optional on bleeding
edge; after this lands and I can do so safely, I'll remove the
argument from bleeding edge.)

Also bump the analyzer version to 0.32.5 so we can publish this
