[flexiglass] Use SecureTextField for PasswordBouncer 

This CL updates PasswordBouncer to migrate from TextField to a SecureTextField so that the password's last character is visible while typing (see TextObfuscationode.RevealLastTyped). With b/416411014 this will also respect the System.TEXT_SHOW_PASSWORD setting then.

SecureTextField uses TextFieldState instead of a value and onValueChange, so I had to make some more changes than initially planned.

I've also updated the tests for other bouncer related views to validate that the onIntentionalUserInput lambda is being called correctly.
