Node: add xlayer tokens to manual token list (wormhole-foundation#3926)

* node: add x layer tokens to manual_tokens.go

- Coin Gecko IDs left blank here because there is no entry for these
  tokens yet
- Prices are taken from the chain explorer directly

* node: Update X Layer manual token list

- Fix Chain ID
- Add more tokens with >50k daily volume
- Add CG IDs for tokens that have them
- Add commented out tokens that have high volume but no CH entries
- Update prices (use CG price where available)

* node: remove tokens without CoinGecko IDs
