Reuse the same contract address when upgrading ERC->CW pointers

[codchen]

Describe your changes and provide context

Previously pointer contract will be assigned a new address when it's upgraded to a new version, which is quite inconvenient to end users and applications. Since pointer contracts themselves are stateless, it is possible to reuse the same address for a new version of code. This PR implements that for the EVM->CW direction pointers. A similar change will be made for CW->EVM pointers
