docs(jsdoc): add JSDoc for Middleware

[yusukebe]

In this PR, let's write the JSDoc for all builtin Middleware. Only Middleware is addressed here; other documentation than Middleware is done in other PRs. Example #2677.

Will fix #1338

Hi @goisaki

Great! It will be super helpful.

Could you create the PR based on this jsdoc-middleware by each middleware?
