chore: show multichain network icons

[micaelae]

Description

This adds the multichain network icon mapping to the getImageForChainId function so network icons can be displayed for non-EVM assets

Related issues

Fixes:N/A

Manual testing steps

1. EVM network asset pickers should not be affected
2. Changes in multichain networks will only be visible after Swaps/Bridge supports them (separate PR)
