Mezo mainnet deployment (#4378)

* Mezo mainnet deployment

- Provides .env.mezo.mainnet used for deploying WH Core and Token Bridge
  contracts to Mezo Mainnet

* Add Mezo mainnet values to node and SDK

Adds support for Mezo on mainnet.

    Core contract here
    Token bridge contract here

To enable Mezo on mainnet, use the following config parameters:

```
--mezoRPC YOUR_MEZO_RPC
--mezoContract 0xaBf89de706B583424328B54dD05a8fC986750Da8
```
