RFR: 8358813: JPasswordField identifies spaces in password via delete shortcuts [v2]

[Jeremy Wood]

> There were a few action bindings available in JPasswordFields in Aqua that let you identify the boundaries of words.
> 
> This came to my attention while looking at the related work https://github.com/openjdk/jdk/pull/25443 . In that PR we said we should iterate across all available L&Fs, so this PR copies that same approach. (The original complaint only focused on Aqua, though.)

Jeremy Wood has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains five additional commits since the last revision:
