Filipe Silva e5905bb035 fix(core): use shakeable global definitions (#29929)
The `ngDevMode` and `ngI18nClosureMode` are special in that they should be set to `false` on production builds in order to shake out code associated with it.

Angular CLI does this in 5fc1f2499c/packages/angular_devkit/build_angular/src/angular-cli-files/models/webpack-configs/common.ts (L279-L282).

But in https://github.com/angular/angular/pull/28689 the toplevel usage was changed from `ngDevMode` to `global['ngDevMode']` (and the same for `ngI18nClosureMode`). This indirection prevents the static analysis in Terser from effecting the replacement.
