cosmwasm-vm needs to be upgraded

[aeryz]

The cosmwasm-vm that is used here is taken from here I guess. Note that this cosmwasm-vm version is outdated, it contains some severe bugs (e.g. admin is incorrectly checked when doing migrate). And the vm implementation is missing some host functions so that if any contract call these, they will likely to be failed or run incorrectly. I would be happy to upgrade the vm implementation that will cover all of the host functions as well as using the most recent cosmwasm-vm.

Thank you so much! However, the extension currently uses @terran-one/cw-simulate for the VM operations. Missed out on cosmwebwasm in the code cleanup 😓
