[PM-17031] Create UI-common (#12831)

Extract core functionality from `libs/angular` to allow teams to depend on `libs/ui-common` instead.

Moves the following functionality to `ui-common`.
- `I18nPipe`. `libs/angular` still has an old copy but `components` depends on the new variant from `ui-common`.
- `safeProvider`, `SafeProvider` and `SafeInjectionToken`. `libs/angular`re-exports these to avoid needing to update all consumers.
