fix(@angular-devkit/build-angular): use workspace real path when not …

…preserving symlinks

When not preserving symlinks (the default), the workspace root path should be converted
to the real path on the filesystem to ensure that resolution of all other path-based build
options reflects the actual location of the files. This ensures that typescript and esbuild
resolve files in a consistent manner and avoids hard to diagnose errors involving missing
files at build time.
