Publish symbols for Hermes onto symbol server

[asklar]

Otherwise people have to rebuild from source every time they want to debug

Note: PDBs used to be included in the Nuget packages, but we removed them to reduce the size of Nuget packages.

If not in the main NuGet package, can they be provided either in a secondary NuGet package or uploaded to MS symbol servers?

It's a common SDL requirement to run BinSkim against the full set of binaries of an application and the tool needs access to PDBs.

Done with #49 and #50
