This pull introduces a `Prefetch` operation in the trie to prefetch trie
nodes in parallel. It is used by the `triePrefetcher` to accelerate state
loading and improve overall chain processing performance.
These changes made in the PR should be highlighted here
The trie tracer is split into two distinct structs: opTracer and prevalueTracer.
The former is specific to MPT, while the latter is generic and applicable to all
trie implementations.
The original values of dirty nodes are tracked in a NodeSet. This serves
as the foundation for both full archive node implementations and the state live
tracer.

* trie: add node type common package
In trie/types package, a few node wrappers are defined, which will be used
in both trie package, trie/snap package, etc. Therefore, a standalone common
package is created to put these stuffs.
* trie: rename trie/types to trie/trienode
