Update protos to IBC v3.0.0-rc.0 and Cosmos SDK v0.45.1

[romac]

Closes: cosmos/ibc-proto-rs#5

Description

• Update Protocol Buffers definitons to Cosmos SDK v0.45.1 et IBC v3.0.0-rc.0

• Remove channel version negotiation step during channel handshake (done in Handle non-standard ports in channel handshake #1840)

  In IBC v2, relayers would query the NegotiateAppVersion endpoint before calling ChanOpenTry.
  Applications would then need to verify that the passed in version was correct.
  As of IBC v3, applications will perform this version negotiation during the channel handshake, thus removing the need for the relayer to query the version.

• Handle non-standard ports in channel handshake (done in Handle non-standard ports in channel handshake #1840)

Super! Left a couple of suggestions for further cleanup, but I think we're pretty much ready.

We should also bump up the IBC_GO_MODULE_VERSION_REQ to match ibc-go v3

Looks good, awesome work Romain!

I think we still have 3 sets of COSMOS_IBC|SDK_COMMIT files, would be cool to reduce the redundancy there.

If we decide to do a 0.11.1 release then maybe merge this PR only after the release.

Done :)

We might have moved a bit too fast with upgrading the files: https://github.com/cosmos/ibc-go/releases/tag/v3.0.0-beta1. I think we should regenerate the files from v3-beta1, or maybe even better, wait it out until v3 comes out (towards end of Febr)?

At a high level, when comparing to v3.0.0-alpha2 this release:

• addresses all issues raised by Trail of Bits during an audit of ICS27
• simplifies controller chain portID to only contain a prefix and the owner address
• introduces JSON encoded metadata to ICS27 to store the version, connection sequences, encoding/txtype, and the interchain account address
• the ics27 host chain will include the MsgResponse in the packet acknowledgement upon successful transaction execution. Please see the auth module documentation for more information.

Sure, that was expected. We don't want to merge this before v3 is out anyway :)

LGTM!

We'll do more extensive manual testing, and also give the master branch for testing to a couple of operators once this is merged.

Great work Romain!
