Potential jank caused by TtsHostMsg_InitializeVoiceList

Project Member Reported by etienneb@chromium.org, Jul 31 
Slow-reports is shipped back to our server with a chrome trace when some jank is detected on the chrome main thread.

The jank is probably caused by slow calls to libraries:
See TtsMessageFilter::OnInitializeVoiceList()

See attachments.
