Support ENS resolution on any EVM compatible chain (including L2s)

[bschorchit]

Background

Currently ENS resolution is only supported on Ethereum mainnet. This issue addresses extending support for it for any EVM network supported by ENS.

Acceptance Criterias

1. User facing functionality for ENS resolution that currently exists for Ethereum Mainnet is replicated for all ENS-supported EVM compatible chains in MM
2. When a network doesn't have ENS support, the Network does not support ENS warning is shown when the user tries to input an ENS name on a send flow
3. We should test this with Linea test network (once it has ENS support) and confirm it's working

Repro Steps

1. Click on Send
2. Input an ENS address such as Vitalik.eth
3. See ENS resolved to the correct registered address if you're on Ethereum Mainnet, Goerli or Sepolia or see the Network does not support ENS warning if you're on a different network

Hi @bschorchit - I wanted to ask if there are any updates on this issue? It seems like a widely requested one (see for example 12990) and important for good L2 UX
