Remove an unneeded std::move(), found by clang/win.

https://codereview.chromium.org/1530923002 changed this from a Pass() to
std::move(), which has the effect that the compiler can now reason about it
and is able to point out:

..\..\ui\gfx\win\direct_manipulation.cc(21,10) :  error: moving a local object
      in a return statement prevents copy elision [-Werror,-Wpessimizing-move]
  return std::move(instance);
         ^
..\..\ui\gfx\win\direct_manipulation.cc(21,10) :  note: remove std::move
      call here
  return std::move(instance);
         ^~~~~~~~~~
