Add QFileInfo::readSymLink() to read the raw link path

The existing symLinkTarget() always resolves the symlink target to an
absolute path; readSymLink() provides access to the relative path when
that is how the symlink references its target.

[ChangeLog][QtCore][QFileInfo] Added readSymLink() to read the symlink's
raw target, without resolving to an absolute path.

Fixes: QTBUG-96761
