Import / Export router state

[akku1139]

What is the feature you are proposing?

Hono's RegExpRouter is fast, but it has the disadvantage that route registration is slow.

RegExpRouter is fast, but the route registration phase can be slightly slow.

Hono Docs - https://hono.dev/docs/concepts/routers#linearrouter

This proposal is part of the RegExpRouter acceleration.

1. Export routes and RegExp when building Hono application.
2. The built application imports routes and built RegExp.
3. The route registration phase is skipped when the application boots.
4. Very fast startup with RegExpRouter is achieved.
