RFR: 8340466: Add description for PassFailJFrame constructors [v2]

[Alexey Ivanov]

> I added description to all the constructors available in `PassFailJFrame`.
> 
> I generated the javadoc for it: [`PassFailJFrame` constructor details](https://cr.openjdk.org/~aivanov/PassFailJFrame/api/PassFailJFrame.html#constructor-detail) which is easier to read. This hosted javadoc could be used as a reference to its API.
> 
> The constructor with the largest number of parameters contains a short description of how to use the `PassFailJFrame` object.
> 
> Shall we deprecate the constructors in favour of `Builder`?
> 
> The builder provides a more streamlined experience, therefore new tests should use it instead of constructors. We may update the tests which use the constructors, after which the constructors can be removed.

Alexey Ivanov has updated the pull request incrementally with one additional commit since the last revision:

  Use EDT abbreviation in constructor description

  the top-level doc comment.
