This is a reland of 856342886a
The waterfall reveals that `cpu_instructions` and `cpu_cycles` are
not populated prior to macOS 10.15. This CL updates expectations
accordingly.
Original change's description:
> [battery] Add ResourceCoalitionMacTest.Busy.
>
> This test verifies that CPU instructions, CPU cycles and CPU time
> reported by `GetCoalitionResourceUsage` increase after burning CPU.
> This is a basic expectations for `GetCoalitionResourceUsage` so it
> should be tested from //components/power_metrics/. In an upcoming
> CL, this will allow removing
> //chrome/browser/performance_monitor/resource_coalition_mac_unittest.mm
> without losing tests.
