Murisi/borsh ibc msg transfer rebase v0.41.0

[murisi]

Describe your changes

Attempt to close #3501 and hence simplify the (de)serialization of IBC transactions for third parties. More specifically, the following changes have been made:

• IBC transaction data is now always a tagged serialization of the IbcMessage enumeration instead of being an untagged serialization of a MsgTransfer, MsgNftTransfer or Any structure.
• IBC transaction data is now encoded using Borsh serialization instead of Protobufs. This is more consistent with how all the other parts of a Tx are serialized using Borsh, and will ease schema generation.
• Updated the test vector generation code (i.e. the generator and the vector printer) to produce transactions in accordance with the above two changes.

What is the status of this @murisi?

can we close this? @murisi

can we close this? @murisi

Yeah, we can close this. But for the sake of consistency, in the future we should probably consider using Borsh (de)seralization for the IBC messages and also tagging them to bring their encoding into line with the rest of the Namada transactions. That being said, this might be more trouble than it's worth given that the hardware wallet integration of this Protobuf encoding (wrapped by a Borsh encoding) has already been implemented on the hardware wallet.
