chore: Move existing middlewares to a middlewares folder and added pass through middleware for packages (#39410)

## Description
Move middlewares to a new folder and added an ee specific middleware
`app/client/src/ee/middlewares/PackageMiddleware.ts`.
This will eventually be added to the store but as of now it is detached
since the functionality is incomplete. It will be extended in EE
