Expand description

Create a new on-chain database instance for the calling contract. When created, push it to the list of db_handles.

This function expects to receive a pointer from which a ContractId and the db_name will be read.

This function should only be allowed in ContractSection::Deploy, as that is called when a contract is being (re)deployed and databases have to be created.
