feat: ability to test Pop API features locally using Pop CLI

[brunopgalvao]

As an avid Pop API fan, I would really like the option to deploy to a cross-chain, Pop API compatible chain (Pop) so that I can test ink! smart contracts that use the Pop API.

For example:

pop up contract

┌   Pop CLI : Deploy locally
│
◆  Select the node to spin up and deploy:
│  ● substrate-contracts-node (solochain)
│  ○ Pop (Polkadot)
