Building .NET Framework libraries fails: error CS0006: Metadata file 'System.EnterpriseServices.Wrapper.dll' could not be found

[sin-ack]

This error seems to happen because of the fix done to solve #405:

rules_dotnet/dotnet/private/rules/nuget/nuget_archive.bzl

Lines 155 to 157 in 54cf66c

	# See https://github.com/bazel-contrib/rules_dotnet/issues/405
	if not file.endswith(".dll") or file.endswith(".resources.dll") or file.endswith("System.EnterpriseServices.Thunk.dll") or file.endswith("System.EnterpriseServices.Wrapper.dll"):
	return

This causes the following problem:

error CS0006: Metadata file '/tmp/bazel-working-directory/_main/external/_main~targeting_packs_extension~nuget.microsoft.netframework.referenceassemblies.net48.v1.0.3/build/.NETFramework/v4.8/System.EnterpriseServices.Wrapper.dll' could not be found

However, naively removing this check fails with:

error CS1509: The referenced file '/tmp/bazel-working-directory/_main/external/_main~targeting_packs_extension~nuget.microsoft.netframework.referenceassemblies.net48.v1.0.3/build/.NETFramework/v4.8/System.EnterpriseServices.Wrapper.dll' is not an assembly

This is because System.EnterpriseServices.Wrapper.dll is not an assembly, but a "module", which is a collection of IL code without an assembly manifest (why this is even a thing is an exercise for the reader). It appears that we need another kind of entry beyond "lib" and "ref" called "module", and this library should be added with -addmodule:.

Ok, this sounds like a more principled fix than the previous one. Is there any way to detect that a dll is a module? Maybe paket2nuget would have to figure out what DLLs are modules and pass that to the nuget_repo as a new attribute.
