Subject: fix(compile): inline symlinks as files outside node_modules dir and
 warn for directories (#19285)

If a symlink within the `node_modules` directory lies outside that
directory, it will now warn and inline the file. For directories, it
will just warn for now.

Probably fixes #19251 (I'm still unable to reproduce).
