/**
 * The `NG_ENV_ID` field on a DI token indicates special processing in the `EnvironmentInjector`:
 * getting such tokens from the `EnvironmentInjector` will bypass the standard DI resolution
 * strategy and instead will return implementation produced by the `NG_ENV_ID` factory function.
 *
 * This particular retrieval of DI tokens is mostly done to eliminate circular dependencies and
 * improve tree-shaking.
