Issues with upgrading chiba-clonk to our nascent, smt-compatible, 0.46.0 version of the SDK

[i-norden]

The main issue is that the v0.46.0 version of the SDK is missing the x/auth/ante and x/auth/legacy pkgs. Additionally, we need to use an updated version of ibc-go that works with our 0.46.0 branch of the SDK. There is a PR on ibc-go for updating it to work with 0.46, but this is for a version of 0.46 that does not include our SMT updates. This branch is incompatible with our SMT branch of the SDK until we rebase it to a more recent commit that includes the x/gov/types/v1 pkg.

• Rebase our SDK branch on latest commit of nascent 0.46 (rebase the code on https://github.com/vulcanize/cosmos-sdk/tree/release-v0.46.0-smt-0.0.1-alpha to the version of SDK being used by deps: upgrade of SDK to 0.46 and tendermint to 0.35 cosmos/ibc-go#1205)
• Fork ibc-go, update ibc-go branch to work with release cut for above SDK rebase
• Needed to cut out dependency on auth/ante, we need to add this back in after resolving the dep issue

In the meantime, we have a release of the chiba-clonk that is updated to the v0.12.2 version of ethermint, but lacks SMT integration.
