refactor(@angular/cli): support custom temporary directory in package manager abstraction

This change introduces the ability to specify a base temporary directory when creating a `PackageManager` instance. This allows for creating temporary directories within the project structure (e.g., `node_modules/.tmp`), which enables package managers to correctly inherit project-specific configurations like `.npmrc` or `.yarnrc` during operations like `acquireTempPackage`.
