[Android] Properly remove SuggestionSpan after composition

This CL:

1) Reads Spanned#SPAN_COMPOSING from Java side and propagate it to
   Blink (SuggestionMarker).
2) Removes SuggestionMarker which has this flag after IME done with
   composition.

We want to remove these SuggestionMarkers for
- InputConnection#commitText()
- InputConnection#setComposingText()
- InputConnection#finishComposing()

Note that before caret move event is covered by finishComposing().
