Added section on Model Context Protocol (MCP) support and its benefits.
## Overview
This PR makes the langchain-mcp-adapters package easier to find. It adds
a new “Model Context Protocol (MCP)” section at the top of the
Integrations Overview page.
MCP support was only previously mentioned in a tip block. This made it
hard for developers to find when looking for integration options. This
update shows that MCP is an important integration. It also explains its
purpose and value for users of LangChain and LangGraph.

* significant cleanup of API ref -- only listing init functions, also
cleaning up tables of refs to various middlewares
* breaking out middleware page into a middleware section with
* overview
* custom middlewares
* prebuilt middlewares
* custom middleware has consolidated content in python re "decorator vs
class based" syntax
* opted to keep config options bc we don't have great API refs for js
still todo:
* general editing
* I think we really want to focus on the "one liner" intros to each
prebuilt
* determine structure for individual middleware sections (do we like
what's here? maybe we don't need the extended examples?)
* need help w/ structure on the index page -- need more conceptual copy
I think?
* we have a diff HITL page that only uses this middleware, what to do
about consolidation there?
* api refs for js
