Prepare FlowEVMBridgeHandlerInterfaces for dependency migration

[sisyphusSmiling]

Issue To Be Solved

In order for handled tokens to integrate with the bridge, they will need to implement FlowEVMBridgeHandlerInterfaces.TokenMinter in their minter resources. It will be easiest for them to do this before network migration, and in order to do so, a Cadence 0.42 version of the contract will need be deployed to Testnet. This contract will also need to be staged so the contract and its dependencies can be migrated.

Tasks

Preview Give feedback

1. Create a feature branch containing a version of FlowEVMBridgeHandlerInterfaces that is compatible with Testnet Cadence and current deployments of the EVM contract - likely just containing the TokenMinter resource interface
2. Deploy this contract to Testnet
3. Stage the 1.0 version on Testnet
