Added GPU stat for whether a GPU can report context lost.

On Windows it checks to see if the IDirect3D9 object supports Vista and later features (meaning it won't routinely report lost contexts). On Linux and Mac we can just check if its EGL versus some other GL that doesn't report lost contexts.

I routed the stats to the renderer process so webkit code can query whether lost contexts are likely.

I didn't wire up breakpad yet.
