Add ui_unittests to GN build.

Add ui_unittests to GN build.

Adds os_exchange_data_win_unittest.cc to Windows (it was incorrecly excluded before). Fixed a compilation error in that file.

Remove special filtering out in GYP build of base/ime/chromeos/character_composer_unittest.cc and base/ime/input_method_chromeos_unittest.cc since the standard filtering patterns match both of these.

We should be building this test on Aura Win.

I put back the exchange data file and fixed the syntax error it in.

Thanks for fixing this. It's frustrating that codesearch is missing random
files; since os_exchange_data_provider_win.{cc|h} don't show up there, I was
wondering how we had gotten rid of this code without breaking things =)
