separate picture info from cc.debug

separate picture info from cc.debug

cc.debug includes pictures, resources and other layers info.
a picture has skia data which is encoded by base64 format.
the skia data is too big to send via IPC. so we can not see
other tracing info. this patch is for separating the picture
data from cc.debug.

And I am trying to flush the buffer frequently if it is possible.

Is it safe to say that this change will only change the checkboxes behavior in
tracing? Ie, the code that parses out the picture doesn't rely on this name. Is
that correct?

yes, that's correct. but trace-viewer has a small issue 
which is no exception-handling about having a picture layer which has no
pictures.
so I uploaded the patch( https://github.com/google/trace-viewer/pull/712 )
