Handle arbitrarily long symlink target in `expandSymlinks()` (#23650)

For now, `expandSymlinks()` can handle only symlinks with lengths up to
1024.

We can improve this logic and retry inside a loop with increasing
lengths until we succeed.

The same approach is used in
[Go](https://github.com/golang/go/blob/377646589d5fb0224014683e0d1f1db35e60c3ac/src/os/file_unix.go#L446),
[Rust](https://github.com/rust-lang/rust/blob/785eb65377e5d7f8d8e8b82ede044212bbd2d76e/library/std/src/sys/pal/unix/fs.rs#L1700)
and [Nim's
`getCurrentDir()`](https://github.com/nim-lang/Nim/blob/devel/lib/std/private/ospaths2.nim#L877),
so maybe it's a good idea to use the same logic in `expandSymlinks()`
also.
