3. refactor(db): add disk serialization types for transactions (#3741)
* refactor(db): simplify block height serialization

* refactor(db): make height serialization length generic

* refactor(db): create a TransactionIndex type

This changes the names of some snapshot types,
but doesn't change any data.

* refactor(db): create transparent OutputIndex and OutputLocation types

This keeps the same serialization, to avoid changing the database version.

* doc(rfc/db): make transparent database type names consistent

* doc(rfc/db): fix a bug in the Utxo.is_coinbase derivation

* fix(db): use the correct serialized size for OutputLocation
