Make the bridge_id in WebGeolocationPermissionRequestManager be unique per process.

Right now it's unique per view, but as part of converting the content side code to use frames instead of views in https://codereview.chromium.org/303503008/ we need this to be unique per view. That can change back in the future once all the permission-related code in the browser (PermissionRequestID in particular) is converted.
