refactor(@angular-devkit/build-angular): remove direct import of i18n worker code

The i18n inlining worker code was previously imported in several locations to allow
reuse of the options object used to configure the worker. To prevent the worker
code from being used outside of an actual worker, the options object definition is
now located in a separate file and imported in both the worker and any other files
that need to use the inlining options.
