Upgrade googletest to most recent upstream version.

Changes needed to complete the upgrade:

- Bump GMock C++ version to C++14.
- Set gmock_tests to C++14 to work around an issue with
  ExpectCallTest.NonMoveableType, which fails to compile
  with the current AOSP compiler.
- Disable -Wthread-safety-negative for the Notification type
  (breaks code that enables -Werror).
- Disable -Wfloat-equal in AppropriateResolution (ditto).
- Disable -Wuser-defined-warnings for the pointer printer
  to avoid errors in mock methods from the std namespace
  manipulation in android-base/logging.h.
- Temporarily add an inclusion of <iomanip> to
  gtest/internal/custom/gtest-port.h. This header was previously
  included by gtest/internal/gtest-internal.h and many tests
  do not include it explicitly.
- Remove the newline added in AddTestPartResult so that the
  golden output tests in gtest_isolated_tests do not break.
