Remove references to GlobalAssemblyCache #772

The GAC is not supported in .NET Core - Assembly.GlobalAssemblyCache always returns false, for example.

Therefore this is all dead in .NET Core. However, there may be a breaking change. Consider that the user defines their own non-runtime assembly by directly subclassing Assembly instead of using typeof(int).Assembly for example. If they overrode GlobalAssemblyCache to return true in .NET Core then the code that I deleted would have been run. However, the entire GAC feature has been removed in .NET Core so I firstly don't see this happening and secondly the code is actually meaningless anyway.

In ResXDataNote.cs we have the following code:

            if(result != null) {
                // Only cache types from .Net framework  because they don't need to update.
                // For simplicity, don't cache custom types
                if (IsNetFrameworkAssembly(result.Assembly.Location)) {
                    cachedTypes[name] = result;
        /// <devdoc>
        /// This is matching %windir%\Microsoft.NET\Framework*, so both 32bit and 64bit framework will be covered.
        /// </devdoc>
        private bool IsNetFrameworkAssembly(string assemblyPath)
            return assemblyPath != null && assemblyPath.StartsWith(NetFrameworkPath, StringComparison.OrdinalIgnoreCase);

This code refers to the .NET Framework (which is obviously not .NET Core). Should it be removed?

@hughbe #485 is a task to remove framework isms. If you'd like to venture such a PR, you are welcome to. However, I think this will be a bit tricky and will not simply be a matter of deleting all references and references to those references.
