community: Add Naver chat model & embeddings

[hyper-clova]

Description

• Naver HyperCLOVA X community package
  • Add chat model & embeddings
  • Add unit test & integration test
  • Add chat model & embeddings docs
• I changed partner package(partner: Add Naver partner package v1 #24252) to community package on this PR
• Could this embeddings(Add Clova Embeddings for LangChain Community #21890) be deprecated? We are trying to replace it with embedding model(ClovaXEmbeddings) in this PR.

howdy! could you reopen this from a personal repo instead of an organization one? https://python.langchain.com/v0.2/docs/contributing/faq/#how-do-i-allow-maintainers-to-edit-my-pr

this helps us collaborate on the code in your PR :)

one question on namespaces - would it make sense to have these in .clova namespaces instead of .naver?

also, could you clarify the difference between ClovaEmbeddings and ClovaXEmbeddings?

another PR(#25162) is reopen.

I would like to keep it as is, unless it is essential to unify the package name.
(ClovaX is a branding for the model, and I plan to add other models and components. They need to be managed as separate classes.)

also, could you clarify the difference between ClovaEmbeddings and ClovaXEmbeddings?

There are 3 models that are being serviced by embedding, and all are supported in the current PR. In addition, all the functionality of CLOVA Studio that serves actual models, such as distinguishing between test apps and service apps, is supported. The existing PR does not support this content because it is hard-coded.
