Settings: Prep work for JS type checking of various privacy tests

Specifically:
 -  Fixing several type violations and adding JS type checking for
    - test_site_settings_prefs_browser_proxy.js
    - test_local_data_browser_proxy.js
    - test_util.js
 - Removing usage of mockMethods() from
   TestSiteSettingsPrefsBrowserProxy, as this pattern is incompatible
   with static type checking.
 - Updating various js_library() targets with missing dependencies as
   needed.
