all: remove database commit callback, rework noderesolver (#26637)

This change ports some changes from the main PBSS PR:

  - get rid of callback function in `trie.Database.Commit` which is not required anymore
  - rework the `nodeResolver` in `trie.Iterator` to make it compatible with multiple state scheme
  - some other shallow changes in tests and typo-fixes
