Implement UnliftedDatatypes

Note: f8c6fce4 and !5440 (closed) wrongly refer to this ticket instead of #19623. If you got here by following the reference in the commit message, see #19623 instead.

GHC proposal #265 defines the UnliftedDatatypes extension.

This ticket tracks the implementation of said extension.
