Closes #4411

Refs #1007

## Description

deprecation & removal of multisig. This key was only used in the sdk and now it has been added there

Closes: #4715 
Closes: #2163

## Description

In https://github.com/tendermint/tendermint/pull/4466 a new type was created (EventAttribute) that replaced KV.Pair. This made the type Pair deadcode, this pr removes that type.

I don't think a changelog entry is needed since it is not being used anymore. But will add a section to the upgrading.md to let users know that it was replaced
