Optimize the web server size (#34242)
Related to #34185, this PR reduces the size of chunk that contains web-server.ts from 1.14mb to 210.8kb, by splitting base-http and api-utils into different environments.

Only affected thing is we can't have SSG preview mode for the web runtime via `getStaticProps`.
