chore(ci): refactor cpu benchmarks workflows

Following the same pattern as GPU benchmarks, CPU benchmarks rely on a common workflow. Weekly benchmarks are all gathered in one place. Also, all the manual launches via workflow_dispatch event are now done in one place. That way, one doesn't have to browse the workflow tree to find the right CPU benchmark to trigger.
