Standarize asset selection

[dudo50]

Describe the bug
There are assets that have same name which makes it difficult for other devs to map them into SDKs

Expected Behavior
eg - first WETH can stay WETH and the other one can be for example WETH.e or something else, just do not allow duplicates please, as it complicates things a lot.

Current Behavior
Our XCM SDK fails with error because there are multiple assets of same symbol - eg. WETH
WETH - 0x5a4d6acdc4e3e5ab15717f407afe957f7a242578, WETH - 6

Expected status
Please differentiate assets in asset registry and do not allow for registering same asset symbol.

Thanks in advance!

well, you are going to be able to handle duplicated symbols eventually. but in this case, the AH WETH isn't used so we can rename it to WETHah if that helps

Yes, any duplicit asset resolving will help. Thanks!
