Add support for Power Word: Shield absorb

Not sure if this is something you are looking to implement, but I saw Vuhdo is working on a method to implement this here: https://gitlab.vuhdo.io/vuhdo/vuhdo/-/merge_requests/62/diffs

Bump on this feature request, apparently unit aura carries absorb amount since the cata prepatch. Grid just added support for it https://github.com/michaelnpsp/Grid2/commit/4efe5eb97d6102ffa8899524729f720b36614202
