Deprecate mRequestUpdateCursorAnchorInfoMonitorMode part 2

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.
