7498491: update process_id to use OriginatingProcess type

The upstream Chromium API changed - URLLoaderFactoryParams::process_id
was changed from an integer to a union type network::OriginatingProcess
that distinguishes between browser and renderer processes.

- For browser process requests, use OriginatingProcess::browser()
- For renderer process lookups, check !is_browser() and use
  renderer_process().value() to get the child_id
