Fix brave/brave-ios#8435: NFT images failing to show in Activity tab …

…Send transactions (brave/brave-ios#8436)

* Store optional `NFTMetadata` in `SendDetails` (Solana NFT), and `Eth721TransferDetails`. Fetch NFT metadata on Activity tab and use for NFT icon display.

* Update unit test to include nft transaction and verify NFTMetadata is fetched.
