[feat] add transfer to .cfx domain owner (similar to .eth domain transfers in metamask)

[HannesGitH]

Problem:
I want do be able to send tokens to the owner of a .cfx domain, similar how metamask users can tranfer token to .eth domain owners.
Therefore no need to copy or type complex non-human readable addresses but simple domain names for transactions.

Solution:
Instead of showing "Recipient address is invalid" when typing e.g. "conflux.cfx", query the conflux domain name service nft contract to resolve the owner of a .cfx domain, show this owner in the portal and continue the tranaction

this should be tackled after CIP-46 is implemented
