Implement InputConnectionWrapper#takeSnapshot()
This is a follow up CL to my previous CL [1], which forgot to
implement
InputConnectionWrapper#takeSnapshot().
As a result, it has alreays returned null even if the wrapped
InputConnection does implement InputConnection#takeSnapshot(). This
means that InputMethodManager#invalidateInput() had always fallen back
to slow InputMethodManager#restartInput() path if an app returned a
wrapped InputConnection for example.
With this CL, wrapped InputConnection can also start taking advantage
of fast restart-input mechanism unless it's further overridden by the
app developer to return null for some reasons.
