Add cloud symweb support

Add back -mi (add symweb symbol server), -nocache and -interface options to setsymbolserver command. Add back --internal-server support to dotnet-symbol. Clean up the HttpSymbolStore.cs - fix HttpResponse not being properly disposed. Removed the separate authenticated client instance/var. Fix dotnet-symbol for some heap dumps. Some didn't have coreclr.dll's debug directory contents. Catch error and continue downloading files.
