JDK-8264274: Block tags in overview.html are ignored

[hns]

This is a simple fix to generate block tags in overview files specified by the -overview option.

I added a protected addOverviewTags method in AbstractOverviewIndexWriter which is probably overkill but keeps things flexible and separated.

src/ code looks good; test/ code has a question...

[jonathan-gibbons]

What's with the funky URL?

[hns]

That's just a format string specifier "%1$s", meaning the first format argument (see invocation of formatted method below to adapt the string to a module or non-module context).

I realize now that I could have omitted the argument index part of the format specifier, will update the PR if that is true.

[jonathan-gibbons]

Doh, silly me; of course.
