Supersedes: #2704

• https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-24112

Our SDK has an implicit reference to System.Drawing.Common:

• Microsoft.ApplicationInsights.PerfCounterCollector
  • System.Diagnostics.PerformanceCounter https://www.nuget.org/packages/System.Diagnostics.PerformanceCounter/4.7.0
    • System.Configuration.ConfigurationManager https://www.nuget.org/packages/System.Configuration.ConfigurationManager/4.7.0
      • System.Security.Permissions https://www.nuget.org/packages/System.Security.Permissions/4.7.0
        • System.Windows.Extensions https://www.nuget.org/packages/System.Windows.Extensions/4.7.0
          • System.Drawing.Common https://www.nuget.org/packages/System.Drawing.Common/4.7.0

We could mitigate this by taking a dependency on System.Drawing.Common v4.7.2.

Instead, we're going to upgrade System.Diagnostics.PerformanceCounter from v4.7.0 to v6.0.0 to get a version of System.Drawing.Common without a vulnerability.
