Fix stats counters

Fix stats counters

- intialize the V8 callbacks first thing, otherwise, the counters disable themselves
- don't use inline event handlers in the presence of a CSP
- on linux, the child processes need to use the parent's parent pid to derive the table name (the parent is the zygote, the parent's parent is the browser)

BUG=none
TEST=run chrome with --enable-stats-table, you should see lots of V8 stats, and you should be able to filter for e.g. V8

File content/renderer/render_thread_impl.cc (right):

content/renderer/render_thread_impl.cc:188:
v8::V8::SetCounterFunction(base::StatsTable::FindLocation);
V8 counters only try once to lookup themselves up, so we need to do this first
thing. In EnsureWebKitInitialized, it's too late
