SettingsSplit: Remove unnecessary 'preprocess' attributes from grd

By searching the settings/chromeos folder [1] for the string "<if" [2],
I determined that there are only 4 files in it that have conditional
tags that require preprocessing, namely
-settings/chromeos/os_settings.html
-settings/chromeos/os_about_page/os_about_page.js
-settings/chromeos/os_about_page/os_about_page.html
-settings/chromeos/os_privacy_page/os_privacy_page.html

I suspect that the preprocess attributes were just not deleted when
those files were branched from browser settings.

This CL removes the preprocess=true attribute from every file from the
chromeos folder [1] in os_settings_resources.grd other than the 4
aforementioned files. It also adds preprocess="true" to
os_privacy_page.html, which has "<if expr..." conditional content but
did not have the attribute.
