[HBD] Fix Widevine breakage introduced by prior patch

Breakage introduced by prior patch here:
https://codereview.chromium.org/2208463002

We had split off GetPluginContentSetting into a utils file, but
forgot to add the widevine header file include.

This means that WIDEVINE_CDM_AVAILABLE is never defined, and the
Widevine-treated-as-JavaScript for content settings clause is
never activated, breaking Widevine on Corp machines.
