By using the `strings` re-export from `@angular-devkit/schematics` instead of from `@angular-devkit/core`,
the number of imports from `@angular-devkit/core` has been reduced and lowers the direct dependency count
for many of the individual schematics.
With this change we removed several deprecated `@schematics/angular` deprecated options.
BREAKING CHANGE:
We removed several deprecated `@schematics/angular` deprecated options.
- `lintFix` have been removed from all schematics. `ng lint --fix` should be used instead.
- `legacyBrowsers` have been removed from the `application` schematics since IE 11 is no longer supported.
- `configuration` has been removed from the `web-worker` as it was unused.
- `target` has been removed from the `service-worker` as it was unused.
An internal schematics helper rule has been introduced for Angular schematics that only generate a set of project files from a set of templated files. Multiple current generation schematics contained essentially the same code which increased the sustainment burden and made refactoring and improvements more complicated.
