This is the second step towards deprecating
InputMethodManager#mRequestUpdateCursorAnchorInfoMonitorMode,
which was introduced as a minimum implementation to support
CursorAnchorInfo API in EditText [1]
Before this CL, there is a behavior discrepancy in
InputMethodManager#updateCursorAnchorInfo()
handler because mRequestUpdateCursorAnchorInfoMonitorMode has a valid
value when and only when the editor component is EditText.
With this CL, the same behavior will be applied to non-View based
editors.
