Update to Chromium version 97.0.4692.0 (#938553)

- Remove CefRequestContextHandler::OnBeforePluginLoad and
  CefRequestContext::PurgePluginListCache (fixes issue #3047). These methods
  stopped being relevant after the removal of Flash support in January 2021.
  The last remaining PPAPI plugin (PDF viewer) will switch to a non-plugin
  implementation in the near future (see https://crbug.com/702993#c58) and
  functionality related to plugin filtering has already been removed in
  https://crrev.com/343ae351c9.
