media: Enable ProtectedMediaIdentifierPermissionContext on ChromeOS.

media: Enable ProtectedMediaIdentifierPermissionContext on ChromeOS.

Previously ProtectedMediaIdentifierPermissionContext is only used on Android.

In this CL:
- ChromeOS is using the stanand infobar/bubble permission UI.
- ChromeOS is using the same strings as Android. This should be fixed or
  reevaluated. See below.

Follow up work:
1. Make sure the infobar/bubble UI (including strings) is good for ChromeOS.
2. Fix the icon for the infobar/bubble on ChromeOS.
3. If we cannot get (1) and (2) done, use the current ChromeOS UI (see
   PlatformVerificationDialog) for ProtectedMediaIdentifierPermissionContext.
