fix(core-database): decouple database and state packages

[bertiespell]

This proposal looks to decouple core-database and core-state.

It is useful for us to be able to include core-database without introducing a bunch of dependencies. Currently core-database relies on core-state, which in turn relies on lots of other packages. This is especially a problem since dynamic block times, because things like stand-alone forger process now need to look up block timestamps for specific heights (without needing core-state at all).
