all: disable recording preimage of trie keys (#21402)

* cmd, core, eth, light, trie: disable recording preimage by default

* core, eth: fix unit tests

* core: fix import

* all: change to nopreimage

* cmd, core, eth, trie: use cache.preimages flag

* cmd: enable preimages for archive node

* cmd/utils, trie: simplify preimage tracking a bit

* core: fix linter
