Roman Khimov 23464401bc core/state: merge spent and unspent coins state, use it to store more things
This change reduces pressure on DB by doing the following things:
 * not storing additional KV pair for SpentCoin
 * storing Output right in the UnspentCoin, thus eliminating the need to get a
   full transaction from DB

At the same time it makes UnspentCoin more fat and hot, but it should probably
worth it.

Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs
can't come out of nowhere.

1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD,
before:
real    302m9.895s
user    96m17.200s
sys     13m37.084s

after:
real    159m16.551s
user    69m58.279s
sys     7m34.334s

So it's almost two-fold which is a great improvement.
