Fullstate simulator library should not be renamed to Winodws-style dll on non-Windows platforms.

Right now logic exists in our build passes that takes the output from the xplat build of the native simulator and renames all the files into the Windows style, Microsoft.Quantum.Simulator.Runtime.dll. This is unnecessary and causes confusion when working on other platforms. We should remove this rename, and then update the .csproj files in this repo such that local development does not take a dependency on the rename happening. For example, this part of Simulators.Dev.props:

qsharp-runtime/src/Simulation/Common/Simulators.Dev.props

Lines 26 to 32 in 4f32b5b

	<ItemGroup>
	<None Include="$(QSimDll)" >
	<Link>Microsoft.Quantum.Simulator.Runtime.dll</Link>
	<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
	<Visible>false</Visible>
	</None>
	</ItemGroup>

Should be updated to not expect the file with the Windows specific naming and instead use the built-in support .NET has for dynamically loading the right platform specific library.

@cesarzc I believe this is what you have been looking into related to the runtime package in any case.
@swernli Could you please confirm that the updates here are indeed accurate for the currently setup? I am slightly confused by the fact that the PR for the readme is merged but this issue is still open.
