fix(@angular/cli): use project-local temporary directory in ng add

The 'ng add' command now attempts to use '.angular/cache' or 'node_modules' as the base for temporary directories when acquiring packages. This ensures that the package manager can inherit project-specific configuration (like '.npmrc' or '.yarnrc') during the installation of temporary packages.

The implementation uses a fallback strategy, checking for candidate directories and defaulting to the system's temporary directory if none are found.
