chore: set bridge src network, tokens and top assets

[micaelae]

Description

• Implements a selectSrcNetwork bridge controller action, which sets a state value for the cross-chain swaps source network
• On src network change, the controller fetches the bridgeable tokens for the network and also the top assets list
• Adds a call to the useBridging hook within the bridge route, which sets the src network, tokens and topAssets when the bridge experience is loaded

      srcTokens: {
        [tokenAddress.toLowerCase()]: { ...tokenDetails }
      },
      srcTopAssets: [
        // list of tokens sorted by popularity
      ],
    }
  }
}
