core: clone MPT node while restoring it multiple times
...
We need this to avoid collapse collisions. Example of such collapse
described in
https://github.com/nspcc-dev/neo-go/pull/2019#discussion_r689629704 .

core: collapse completed parts of Billet
...
Some kind of marker is needed to check whether node has been collapsed
or not. So introduce (HashNode).Collapsed

mpt: move empty hash node in a separate type
...
We use them quite frequently (consider children for a new branch
node) and it is better to get rid of unneeded allocations.

mpt: refactor nodes serialisation
...
It should be serialised with type in case if it's a children node.
The type can be either HashT or EmptyT.

mpt: implement JSON marshaling/unmarshaling
...
Because there is no distinct type field in JSONized nodes, distinction
is made via payload itself, thus all unmarshaling is done via
NodeObject.

mpt: implement MPT trie
...
MPT is a trie with a branching factor = 16, i.e. it consists of sequences in
16-element alphabet.
