refactor(@schematics/angular): use string helper re-export from @angular-devkit/schematics

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.
