Avoid importing modules/web/middleware in modules/session (#30584)

Browse source 
Related to #30375.

It doesn't make sense to import `modules/web/middleware` and
`modules/setting` in `modules/web/session` since the last one is more
low-level.

And it looks like a workaround to call `DeleteLegacySiteCookie` in
`RegenerateSession`, so maybe we could reverse the importing by
registering hook functions.
