Password manager: Enabling Public Suffix List matching on Windows.

The PSL matching seems to work already on Windows, because it only depends on the platform-independent parts of login_database.cc.

After manually verifying that it works (with a Release ToT build), I'd like to enable it on trunk in this CL.

I will make sure that this change does not propagate to beta and stable before it passes all the reviews in the launch bug (linked from the BUG below).
