Subject: Remove binder-based BufferHub from libui

We are removing Binder-based BufferHub from Android. Please refer to
b/147002762 for details. In short, those services and libraries were
originally created as a major refactor for a future product line. As
part of a strategy shift, these components are no longer needed.

Bug: 147002762
Test: Build and flash blueline
Change-Id: If5e64880911f2271a297b1628079261a4251f9e3
