support: BuildStorage methods to take self reference (#3884)

Browse Source 
* support: BuildStorage methods to take self reference.

There is no reason to consume the GenesisConfig when using it to
initialize a new storage backend. Instead, build_storage and
assimilate_storage now operator on self references.

* Bump node runtime impl_version.
