perf(@angular/cli): avoid eager module loading during global bootstrap

Avoid importing `isWarningEnabled` and `colors` statically in `init.ts`.
Eagerly importing `config.ts` causes `@angular-devkit/core` and its transitive
dependencies (`rxjs`, `ajv`, `jsonc-parser`, and schema registries) to be
evaluated synchronously in the global CLI context before resolving the project
local CLI.

By lazily importing `config.ts` and `color.ts` only when `isGlobalGreater` is
true and a version mismatch warning needs to be issued, cold CLI invocations
avoid evaluating these packages globally during bootstrap.
