Combine necessary file for edge route in size calculation

[eps1lon]

Just including page.js in the size calculation isn't enough since it may require other chunks.

In a Webpack world we'd use the Webpack stats instead for accurate calculations without having to read from the filesystem. Turbopack doesn't have these available so we just read every file listed in the the files entry for that specific route in the middleware manifest.

I know not enough about all these manifest to be able to generalize this so for now this only works for the edge-ssr calculation which regressed in #64798 but wasn't caught since the significant bundle increase was in a different chunk.
