Trie: store self-destructed accounts (#355)
* squash commits

* enable storage cache

* make linter happy

* fix subtree prefix len check

* save cahnges to test master

* remove restriction on prefix len

* fix comparison of last bits

* fix wrong alignment

* remove debug prints

* commit current state

* commit current state

* avoid changing state of resolver from multiwalk

* remove debug code

* remove debug code

* remove debug code

* remove unnecessary copy

* make code more readable

* reduce rebuildHashes initial resolution

* fix test after rebase to master

* make code more readable

* improve pruner

* pruner add IntermediateCache bucket

* fix panic in Walk on short keys

* reduce allocations for storage keys decompression by increasing default buffer size

* re-run CI

* fix iterator behaviour

* rename cache to hash for unification

* re-run ci

* avoid using underlying DB

* hash all subtree nodes before unload

* fix getNode method

* need to check node type, not parent - before put to hashBucket

* return back parent type check, doesn't work without it.

* don't recalculate hash again

* move unloadFunc from trie to pruner

* rename bucket to shorter name

* rename bucket to shorter name

* clean

* rebase to master
