feat: refactor all project ID handling into cerberus

[chris13524]

Validate project ID format, call the registry endpoint (skip validation if endpoint unavailable), and cache the response, in this library.

• Skip project id validation when /internal API fails notify-server#34
• Skip project id validation when /internal API calls reown-com/blockchain-api#120
• chore: handle invalid formatted project IDs reown-com/blockchain-api#279
• bug(identity): endpoint will fail if cache data doesn't deserialize reown-com/blockchain-api#259
• Disable project id validation when /internal API calls fail push-server#126

This issue's PR should be paired with usages in notify-server and rpc-proxy. Issue for tracking usage by rest of services: https://github.com/WalletConnect/infra/issues/16
