fix(@angular/build): always disable JSON stats with dev-server

Browse Source 
When using the development server, the `statsJson` option will now
unconditionally be disabled. The output JSON file is not accessible
with the server and the analysis/generation of the JSON file may
increase the rebuild time. Additionally, the JSON file changes during
a rebuild may unexpectedly cause component HMR fallback to a full
reload due to non-component file changes in the build output.
