[FEATURE] - Make Next-Admin framework agnostic

[foyarash]

Summary

Currently, Next-Admin is made to work only with Next.js. There are not so much places that are heavily tied with Next.js actually:

• routing
• route handlers

This would make a port to Remix quite easy actually, if we are able to abstract the routing logic and the route handlers logic aswell.

• Explore the feasibility
• Extract the routing logic in a framework specific file
• Abstract the route handler logic to use web APIs only (Response instead of NextResponse for example)
