Track Text Selection information in TextInputManager (OOPIF for Android)

Track Text Selection information in TextInputManager (OOPIF for Android)

Currently, TextSelection information is directly tracked by the
platform's RenderWidgetHostViewAndroid. This does not work with OOPIFs
which have their own RWHVCFs.

This CL will route the SelectionChanged updates through the
TextInputManager and then notifies the platform's view about any change
on the page. This has already been happening in other platforms:
  * Aura: https://codereview.chromium.org/2130133004
  * Mac: https://codereview.chromium.org/2240553003

An interactive test related to text selection tracking for OOPIFs is
is also enabled on all platformed now.

Hello Charlie,

Could you please take a look?

[Charlie Reis, 2017-01-25 21:10:48]

Nice, LGTM.  (Seems fine to push those down from RWHVBase to RWHVMac for now,
and remove them in a separate CL.)

Thanks Charlie! I will fix the issue with redundant variables in Mac and perhaps
even close 602427.
