refactor(@schematics/angular): replace devkit path functions with node:path

Continuing the effort to reduce dependencies on `@angular-devkit/core`, this commit replaces path manipulation functions (`join`, `normalize`) with their equivalents from the built-in `node:path/posix` module.

This change affects the `service-worker`, `ssr`, and `web-worker` schematics. Unused imports from `@angular-devkit/core` and other modules were also removed as part of this cleanup.
