Gerardo Salazar aef2a47892 Updates CPU performance metrics gathering approach (#5261) 
* Updates CPU performance metrics gathering for project modernization

  * PerformanceCounters are not supported cross-platform in
    .NET Core/5.0, which requires the use of an alternative method
    in the gathering of performance metrics. Since no exposed .NET API
    exists to gather these metrics without blocking, a new thread is
    created to block the time necessary for the CPU performance to be
    calculated.

* Address review: remove ResetEvent and make CpuPercent atomic

* Dispose of CpuPerformance instance before exiting Lean

* Minor tweak for Task and comment
