Android: Fix input method hints for ImhHiddenText

Browse Source 
If ImhHiddenText is set then that should take precedence over the
other input method hints. Also, certain combinations aren't really
possible. E.g., ImhEmailCharactersOnly and ImhHiddenText doesn't have
its own specific variation on Android.
ImhSensitiveData and ImhNoPredictiveText are also likely to not work
as TYPE_TEXT_FLAG_NO_SUGGESTIONS is normally ignored by Android
keyboards. A common workaround is to use the visible password variation
but since this will force the layout to use latin characters it's not
something we can use as an universal workaround, so users will need to
manually enable it through the environment variable
QT_ANDROID_ENABLE_WORKAROUND_TO_DISABLE_PREDICTIVE_TEXT

Fixes: QTBUG-85787
Pick-to: 6.0 5.15
