Consider using `getAutofillHints()` to determine whether we need to do autofill

**Is your feature request related to a problem? Please describe.**

The Autofill was triggered in the wrong input view, such as Termux's terminal, which set AutofillHints to AUTOFILL_TYPE_NONE.[^1]

**Describe the solution you'd like**

Use `getAutofillHints()` to determine whether we need to do autofill here.

**Additional context**

For all AutofillHints values, see https://developer.android.com/reference/android/view/View#setAutofillHints(java.lang.String[])
For `getAutofillHints()`, I found two, but don't know which one is used by the autofill service, see https://developer.android.com/reference/android/app/assist/AssistStructure.ViewNode#getAutofillHints() and https://developer.android.com/reference/android/view/View#getAutofillHints()

Start by comparing Android's View.getAutofillHints() with AssistStructure.ViewNode.getAutofillHints(), using the Android API references linked in the issue. Review the Termux TerminalView.java example to understand the AUTOFILL_TYPE_NONE case. Done means autofill is not triggered for views without applicable hints and existing autofill behavior remains intact.
