RFR: 8358813: remove more bindings for JPasswordFields in Aqua

[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.)
