Process.StartTime raises an exception on non-windows platforms if the process has already exited, so cache it immediately after starting the FrameworkProcess
Process.TotalProcessorTime raises an exception on non-windows if the process has also exited, so don't do that

Add top 20 report when compilation ends for parallel and task executor
Add total cpu usage across all cores when compilation finishes for parallel and task executor
Use real processor time reported by OS when possible to account for internal usage of multiple threads (i.e. cl.exe codegen uses 8 threads)
Enabled by default for Epic developers to increase awareness on most problematic compilation times
