fix(@schematics/angular): remove setting files tsconfig field with SSR/Server generation

The `files` field within the `tsconfig.app.json` file is no longer used
with the "solution" style tsconfig generated with applications. The SSR
and server schematics no longer need to modify this field since all TS
files within `src` are included by default.
