Revert "perfetto: Enable SMB scraping"

This reverts commit 0f6182210893904e32d5d623de12cf0f2a2912b0.

Reason for revert: No effect yet because trace writer registration is still missing in ProducerClient. Will reland once that's fixed, so that any performance regressions are attributed correctly.

Original change's description:
> perfetto: Enable SMB scraping
>
> Enable scraping of shared memory buffers used by the perfetto tracing
> service. This should help reduce missing data in traces. Because of
> that, this change is expected to cause some changes in perf waterfall
> metrics.
