[http-server-csharp] add arrayDeclarationContext

[sophia-ramsey]

In my work in the openai-openapi-pr repo, the service emitter would not compile and gave the following error message:

Error: Emit context must have a scope set in order to create references to declarations.
    at compilerAssert (asset-emitter.js)
    at invokeReference (asset-emitter.js)
    at CSharpCodeEmitter.collectionDeclaration (service.js)
    at CSharpCodeEmitter.arrayDeclaration (service.js)

I fixed the issue when I added arrayDeclarationContext to the local node_modules in my repo. Here is the fix that I made as well as a test that demonstrates the issue.

Thanks for the contribution! A few comments. I think the context is necessary, but the dedicated emitted file is not useful and we should avoid emitting it if possible.

One minor change, otherwise this looks good.
