all: implement path-based state scheme (#25963)
* all: implement path-based state scheme

* all: edits from review

* core/rawdb, trie/triedb/pathdb: review changes

* core, light, trie, eth, tests: reimplement pbss history

* core, trie/triedb/pathdb: track block number in state history

* trie/triedb/pathdb: add history documentation

* core, trie/triedb/pathdb: address comments from Peter's review

Important changes to list:

- Cache trie nodes by path in clean cache
- Remove root->id mappings when history is truncated

* trie/triedb/pathdb: fallback to disk if unexpect node in clean cache

* core/rawdb: fix tests

* trie/triedb/pathdb: rename metrics, change clean cache key

* trie/triedb: manage the clean cache inside of disk layer

* trie/triedb/pathdb: move journal function

* trie/triedb/path: fix tests

* trie/triedb/pathdb: fix journal

* trie/triedb/pathdb: fix history
