Subject: add_contentgpuclient_precreatemessageloop_callback.patch

This adds a ContentGpuClient::PreCreateMessageLoop() callback.
Invoke in GpuMain after SetErrorMode, before starting the message loop.
Allows Electron to restore WER when ELECTRON_DEFAULT_ERROR_MODE is set.

This should be upstreamed.
