Issue

Currently it is hard to debug issues with some parts of qsharp-runtime because not all .pdb and .xml files are included with corresponding .dll files.

How to reproduce

The contents of .nuget\packages\microsoft.quantum.simulators\0.10.2001.2831\lib\netstandard2.1
is the following:

Microsoft.Quantum.Simulation.Common.dll
Microsoft.Quantum.Simulation.QCTraceSimulatorRuntime.dll
Microsoft.Quantum.Simulation.Simulators.dll
Microsoft.Quantum.Simulation.Simulators.pdb
Microsoft.Quantum.Simulation.Simulators.xml

Note that for Microsoft.Quantum.Simulation.Common.dll and Microsoft.Quantum.Simulation.QCTraceSimulatorRuntime.dll both xml and pdb files are missing.
