feat: replace all ModuleCdc instances with legacy.Cdc (#11240)

## Description
Replaces all the various `ModuleCdc` instances with the global `legacy.Cdc` to properly support Amino serialization for the `x/authz` module. This is needed in order to correctly support Ledger signing for `MsgExec` and messages.

Closes: #11232
