Revert of Ensure counters are initialized, to avoid init on non-joinable threads. (patchset #1 id:1 of https://codereview.chromium.org/2812543002/ )

Reason for revert:
https://build.chromium.org/p/client.v8/builders/V8%20Linux64%20-%20gyp/builds/5221

Original issue's description:
> Ensure counters are initialized, to avoid init on non-joinable threads.
>
> This occurs in the wasm scenario described in the referenced bug.
> DecodeWasmModule collects statistics. Blink inserts a CreateHistogramCallback that
> can't instantiate a histogram on non-joinable threads. Turns out, DecodeWasmModule
> is scheduled on such a thread, now that we have async compilation.
>
> This fix pre-initializes histograms when the callback is applied, which is assumed to
> be in a context that can carry out the instantiation. In Blink, this happens on the main
> thread.
