Subject: gpu: notify when dxdiag request for gpu info fails

We rely on the signal OnGpuInfoUpdate to process gpu info.
When Electron wants to collect the complete info in a single run
it checks for the presence of dx_diagnostics attribute, as these
are the only async calls that happens in the gpu process, but
there are times when this call can fail due to crash or software
rendering and there is no signal from browser process on this event
to identify it.
