Move candidate_window from third_party/chromeos_text_input to chrome/browser/chromeos/text_input.

Turned out there is no benefit of having this in a separate git repository.

No code change in candidate_window.cc, but modified the copyright notice
from Chromium OS Authors to Chromium Authors.
Slightly modified text_input.gyp to make it compile.

We'll also change cros_deps/DEPS in a separate CL.

BUG=none
TEST=confirmed candidate_window compiles as before.
