Potential memory leak in TtsDispatcher::OnSetVoiceList

Project Member Reported by etienneb@chromium.org, Aug 15 2017 
Traces were provided by mad@, which is running chrome canary with native heap profiling.

Chrome Canary M62, Windows 10

The attached stackframes are showing
  * 120K strings allocated in "TtsDispatcher::OnSetVoiceList" (~4 Meg)
  * 40K blink::WebSpeechSynthesisVoice::WebSpeechSynthesisVoice (~1.6 Meg)

This is leaking about 5.6 Meg in the browser process.

We don't know if it's related, but the renderer process was using 900M.

Erik - we should start thinking about allocating folks to dig into these sorts of bugs.

We are for most of these bugs.
The most common answer is to get a repro.
When it's hard to repro, we are spending some time to try to make a case.

But, if you know the right people to assign them... feel free. :)
