RFR: 8303480: Miscellaneous fixes to mostly invisible doc comments

[Pavel Rappo]

Please review this superficial documentation cleanup that was triggered by unrelated analysis of doc comments in JDK API.

The only effect that this multi-area PR has on the JDK API Documentation (i.e. the observable effect on the generated HTML pages) can be summarized as follows:

Notes
-----

* I'm not an expert in any of the affected areas, except for jdk.javadoc, and I was merely after misused tags. Because of that, I would appreciate reviews from experts in other areas.
* I discovered many more issues than I included in this PR. The excluded issues seem to occur in infrequently updated third-party code (e.g. javax.xml), which I assume we shouldn't touch unless necessary.
* I will update copyright years after (and if) the fix had been approved, as required.
