The initial implementation of sensitive content support on Android (to address #150218) will not implement the autoSensitive mode, where Android uses a heuristic based on autofill hints to detect sensitive content, see https://developer.android.com/reference/android/view/View#CONTENT_SENSITIVITY_AUTO. Once the initial implementation lands, we should consider implementing this mode, which may require usage of additional APIs.

@gmackall has already done some investigation as to how this may be done in flutter/engine@main...gmackall:engine:content_sensitivity_auto_poc.
