      hw_breakpoints: Split hardware breakpoints config
      hw_breakpoints: Migrate breakpoint conditional build under new config
      x86: Allow the user not to build hw_breakpoints
      hw_breakpoints: Breakpoints arch ability don't need perf events
      hw_breakpoints: Only force perf events if breakpoints are selected
      hw_breakpoints: Drop remaining misplaced dependency on perf
