Implement deepseq->{array,containers} dependancy reversal proposal

See also the related #4868 (closed) proposal

Implementing the proposal involves the following steps:

1. make hackage:deepseq a GHC-boot package,
2. remove deepseq dependancy on hackage:array and hackage:containers,
3. move (and refactor) the affected instance definitions to the array and containers packages respectively (and make them depend on deepseq), and
4. satisfy the PVP by incrementing package versions where necessary.
