ui: Stop depending on packed_resources target directly.

app_list_unittests and message_center_unittests target do not need to
depend on chrome/chrome_resources.gyp:packed_resources directly
because they depend on ui/ui_unittests.gyp:run_ui_unittests and that
target is responsible for depending on packed_resources since it is the
driver that loads the pak file when setting up the test suite. With that we can
drop two more deps on it, making run_ui_unittests the only target on
//ui that is still depending on it. In the next patch I'm going
to remove run_ui_unittests's dependency on packed_resources

Fix the Clipboard::GetSequenceNumber for aura.

Previously on aura, the clipboard sequence number was determined by how many
items there were on the clipboard, which isn't a good indicator of state.
This changes it to return an id which is incremented when state changes.
