FRAME: Revamp Preimage pallet to use Consideration (#1363)

Make Preimage pallet use Consideration instead of handling deposits
directly.

Other half of paritytech/substrate#13666.
Depends/based on #1361.

Script for the lazy migration that should be run manually once:
[migrate-preimage-lazy.py](https://github.com/ggwpez/substrate-scripts/blob/master/migrate-preimage-lazy.py).

## TODO

- [x] Migration code.
