fix(zone.js): add missing types field in package.json (#38585)

Close #38584

In zone.js 0.11.1, the `types` field is missing in the `package.json`,
the reason is in zone.js 0.11.0, the `files` field is used to specify the
types, but it cause the npm package not contain any bundles issue, so zone.js
0.11.1 remove the `files` field, which cause the `type` definition gone.

This PR concat the `zone.js.d.ts`, `zone.configurations.api.ts`, `zone.api.extensions.ts`
types into a single `zone.d.ts` file.
