PerfMonitor - Fix enable/disable states (#53957)

Summary:
Pull Request resolved: #53957

There are cases where the overlay can get enabled multiple times, creating more than one view. This change no-ops enabling if the overlay is already enabled and just uses enable/disable for showing/hiding the view.
