mpt: add Size
method to trie nodes
...
Knowing serialized size of the node is useful for
preallocating byte-slice in advance.

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.

Revert "mpt: do not allocate new buffer when updating dirty node"
...
This reverts commit 168ba7960c
.
It seems, there are some problems with it:
`2020-12-25T18:13:07.476+0300 WARN blockQueue: failed adding block into the blockchain {"error": "error while trying to apply MPT changes: unexpected EOF", "blockHeight": 9729, "nextIndex": 9730}`

mpt: do not allocate new buffer when updating dirty node
...
Running time becomes faster under high load while staying the same in
the average case.
Memory allocation done in `Trie` goes down by about ~10% (even more,
actually).

mpt: implement reference counting
...
Also postpone MPT initialization until `storeBlock`
because we need to read-and-check or save info about refcounting
depending on starting height.

`NodeObject` can contain auxilliary fields and shouldn't be used from outside.
