feat(CpuUtils): Allow suites to forbid siblings
Some perf suites use a single unidirectional flow of traffic. On SMT-enabled machines, 1C tests create 2 workers by default. But if there is only one stream/flow, only one worker does useful work. The other worker on the sibling logical core does busy-wait, which provably lowers the peformance. Some suites already set smt_used (as a suite variable) to False for these purposes. This change edits a lower-level L1 keyword to honor this value, and adds the suite variable to single stream (and client) hoststack suites, where the detrimental effect of busy siblings was observed.
