Add Ledger Live support

[eth2353]

Adds proper support for the Ledger Live app (available on desktop and mobile).

This PR:

• adds this wallet as an option
• auto-recognizes the wallet by the window.ethereum?.isLedgerLive attribute
• disables chain switching for this wallet

The functionality can be tested by manually adding a manifest to the Ledger Live app. You can use the following example manifest JSON:

Manifest

{
  "id": "vault-interface",
  "name": "Vault Interface",
  "url": "http://localhost:3000",
  "dapp": {
    "nanoApp": "Ethereum",

      }
    ]
  },
