dotnet-counters should not have a dependency on sos binaries

[noahfalk]

dotnet-counters depends on Microsoft.Diagnostics.Repl, which depends on M.D.DebugServices, which depends on SOS.NetCore amd CLRMD.

Probably this should be fixed by removing the dependency on Repl and directly referencing System.CommandLine.Experimental.
