refactor(x/distribution)!: migrate to collections

[facundomedica]

Description

Closes: #17114 and #16367

• We need to tag collections
• Added WithCollectionPaginationTriplePrefix in types/query
• I have doubts regarding PreviousProposer. Should we do a migration (like in this PR) or an AltCodec that can decode the current and previous formats?

I don't think we can use AltValueCodec here, the reason is simple, AltValueCodec will prioritise sdk.ConsAddress which is bytes, since it's arbitrary bytes even the gogoproto.Uint64Value bytes can fit in, which means that the alternative decoding will never be used. 😢
