fix rewrites to edge routes

[ztanner]

What?

Rewrites to an edge route currently throw an invariant rather than properly serving up the page that is rewritten to.

Why?

The NextRequest object that is provided to the edge route handler contains pathname information only for the "origin" request (e.g., when visiting /one/example which rewrites to /two/example, the pathname is still /one/example. This hits an invariant since the route matcher is unable to find /one/example since it does not exist.

How?

This updates the module wrapper to grab the pathname from the route definition rather than the request object. For dynamic segments, we extract them from request.nextUrl since we know that even if nextUrl is referencing the origin path, the parameters it has are relevant for the rewrite.

This adds the getUtils utility that's also used in base-server to handle the URL normalization, which also provides an interface for normalizing dynamic params from a ParsedUrlQuery.
